Even in high school, many students are faced with the question of how to learn chemistry on their own from scratch, because this science is rarely mastered the first time. School teachers often do not think about the fact that children do not receive all the necessary knowledge to study science at a more complex level. Therefore, the guys do not understand more and more new tasks, concluding that they have a poor predisposition to the subject. In fact, gaps in knowledge may arise not because of problems with thinking, but because of incorrect school teaching methods.

Let's talk about how to learn chemistry yourself from scratch at home. This question is also relevant for school graduates who are planning to take the Unified State Exam and enter universities.

Many students who study at medical universities encounter chemistry every day. And at the same time, not every one of them knew this science well at school. Here is the advice they give to the younger generation:

• To pass the exam, you need knowledge of the entire school chemistry course. But to study at the university you will only need the basics of inorganic science; experienced professors will teach you everything else. Therefore, develop your short-term memory. After passing the Unified State Exam, you will have to throw all unnecessary information out of your head.
• Lessons with a tutor will bring much more benefits than studying on your own. However, if you do not have the opportunity to attend individual lessons, do not despair, because you can learn chemistry on your own, but it will require hard work.
• Remember that humanity has not come up with an even more effective method of studying disciplines than working hard on your knowledge and skills. Constant practice is your key to success.

It is continuity in learning that is the key factor in achieving the goal. To practice effectively, you need to create the appropriate psychological mood.

Many students are concerned not so much with the quality of the knowledge they receive, but with the time it will take to study. Believe me, the more thoroughly you study the basics of science, the clearer the meaning of each equation is to you, the faster you will master more complex topics. In this case, it will be difficult for you only at the very beginning. Get into the essence of the basic concepts, and then the awareness of each chemical law will come to your mind.

Just by not paying attention to deadlines, you can learn chemistry quickly. It’s possible to do this in a month if we are talking about a school course. Typically, students who are preparing to take an exam set this goal. Use the technique suggested below to create the appropriate psychological mood.

Motivation is the key to success

To create appropriate motivation for yourself and maintain it throughout the entire training period, use the following recommendations:

• Set a goal for yourself, formulate it, clearly understanding what result you want to achieve.
• Remember not to try to learn a lot of information in a short time. It will not linger in your thoughts for long, and all the formulas will merge together.
• The theoretical material will not be fully understood by you if you do not consolidate it by solving practical tasks. Plus, your self-esteem will increase significantly if you are a problem solver.
• Arrange tests for yourself in which you will check the degree of mastery of the material.

Chemistry is just science. The human brain is designed in such a way that we can remember and understand absolutely any information. Therefore, stop telling yourself that chemistry is not your thing, then you will succeed.

Be a teacher

As strange as it may sound, you will learn the material best if you explain it to someone. Learned a new topic but aren't sure you fully understood it? Find a person who doesn’t understand it at all and explain to him the essence of the material. Believe me, after this lesson, in which you will act as a teacher, not only your “student” will gain more knowledge, but also you.

Why chemistry is a problematic subject

Usually, chemistry initially does not excite schoolchildren. After the first lesson, most children give up on studying this science, believing that they do not have the ability. This is due to the fact that from childhood we are taught that chemistry is a science that has given humanity a lot of interesting experiments, amazing sights and amazing innovations. When middle school students come to their first lesson, they are prepared to have an unforgettable experience and participate in interesting experiments. Instead, schoolchildren see only dry theory and many incomprehensible problems. They become disappointed in the subject, and when the time comes to take the exam, they realize that they have no knowledge.

This is the fault of adults. The child must understand that spectacles in chemistry are formed through hard work, and only with some effort can interesting experiments be carried out.

Passing the Unified State Exam

Graduates often think about how to learn chemistry on their own from scratch in order to pass the Unified State Exam. The answer to this question is very simple. You just need to study chemistry without thinking about exams. Your knowledge will be much better and deeper if you master the subject for yourself, and not for entering the university. Having delved into the essence of science, following the above tips, you can easily write tests for

Instructions

Understanding the essence of chemical processes is quite difficult. You need to be able to compose chemical reactions, understand the classification and names of substances and compounds, and much more. How to make sure that there is no confusion in your head?
Study the ticket and compare it with what is in the textbooks you have. Look, maybe you don’t have something, and you will need to spend searching for the necessary material in other sources, how much material you have to learn and assimilate in a limited period of time, how many tickets per day you will need to evenly distribute your forces or even provide at the end of the preparation period a certain amount of time to quickly review all the material and analyze and correct any remaining gaps in your knowledge. Memorize everything gradually, especially with regard to those very nomenclature classifications: you should not try to mindlessly memorize the table of prefixes in the names of substances or other materials presented in general lists. Everything needs to be done consistently and thoughtfully. In all such classifications there is a very definite logic that you just need to understand.

Remember that in addition to actually writing the tickets themselves, you may be asked small additional questions or small tasks, usually of high quality, for understanding. If the exam includes not only theory, but also practice, that is, solving problems, then it is better to prepare theory and practice on the relevant topics in a comprehensive manner, rather than learning the whole theory first, and then, if there is time, turn your attention to the problems.

Don’t overload, take rest breaks with a change of activity, but don’t put everything off until the last day or, according to the old tradition, the night).

This concerns the oral exam. If the exam is to be taken in written form, then the problem with additional questions disappears, but at the same time there is also no opportunity to explain something to the teacher in your notes in case of inaccuracies or correct them, therefore, during the written exam you need to express your thoughts extremely clearly, accurately and understandable so as to eliminate any possible ambiguity or ambiguity.

Yes, and of course, the most important thing. Learn to use the periodic table and quickly read information from it. This will greatly help you save time and effort during the exam - it contains a lot of useful data and tips.

Exams are a busy time for schoolchildren, when in a short period of time you try to put into your head what did not fit into your head during the school year. And it’s good if the subject is such that you can read it once and pass it, but you need to delve into sciences such as physics or chemistry.

Instructions

Find out if there will be practical assignments. Usually the highest score is given for their completion, because they show the student’s real level of knowledge. Write down on a piece of paper the main formulas with which you solved the problems in (there are about 10 of them), and memorize them. Don't forget to also learn the units of measurement for results.

Eliminate gaps in writing equations. This will help you in answering both practical and theoretical part. Learn what basic chemical compounds react with and what reaction products are formed. Be sure to bring your solubility chart with you to the exam. Teachers allow you to use it, and this worksheet will help you a lot when writing chemical reactions. It is also worth remembering how to place coefficients in equations, because the correctness of your answer to the problem depends on this.

After you have remembered the material you need to answer the practical task, let's move on to the theory. Take your list of questions and divide all the questions into three groups. The first group will contain tasks on which you cannot answer anything, the second group will contain questions on which you can say at least something, and the third group will include material that you know well.

Now arm yourself with textbooks and notes, and feel free to take on the study of the first group of questions. Even if you don't have enough time for the second and third groups, you will be confident that you can say a few sentences on each question, which means you will pass the exam.

Chemistry is a rather complex academic subject. The Unified State Exam in Chemistry is not mandatory. But it must be taken by those who plan to continue their education in one of the humanitarian areas. If your vocation is biology, medicine, food or chemical industry, as well as construction, then the prospect of the Unified State Exam in chemistry is inevitable. How to prepare for this difficult exam?

Instructions

If you are still in secondary school, but have already made your choice and know that you will take the Unified State Examination, then try to enroll in a specialized class. In such specialized classes, natural science subjects will be taught in depth. If this is not possible, get ready for serious independent work right away. Already from the 10th grade (or better yet, from the beginning of studying a school chemistry course), efforts must be made to ensure that all the necessary information is absorbed in the system.

Strong knowledge is a lot, but it is not all that is needed for a high score on the Unified State Exam. It is imperative to pay attention to the ability to quickly navigate various types of tasks, analyze alternative answers, and make a choice. You also need to learn how to justify your answer with a detailed explanation.

Even school chemistry textbooks memorized by heart are unlikely to give you the required level of knowledge. Therefore, you need to select and study literature that will help you understand and confidently explain how organic and inorganic substances are connected, how the composition and structure of substances affect their properties, what are the features of the mutual influence of atoms in molecules, and much more. It is very important to pay attention to solving problems and performing calculations using chemical equations, including combined ones.

note

Even if a tutor helps you prepare for the exam, remember that he will not be able to take the exam for you. Therefore, regardless of whether you master science on your own or with someone’s help, serious work is required, first of all, from you.

Helpful advice

Be sure to check out the demo versions of the Unified State Exam options from previous years and the current year. Please note that the format of the assignments may change, so only the teaching aids and demo tests of the current year will be relevant. It makes sense to use assignments from previous years for additional training.

Tip 4: How to allocate time when completing Unified State Exam assignments in chemistry

Typically, chemistry is chosen to take the Unified State Exam by graduates who intend to make medicine, biotechnology, chemical technology, etc. their profession. The state exam is usually a serious psychological test. Therefore, in addition to good knowledge of the subject, it is necessary to navigate the structure of the test and skillfully plan the time allotted for the exam.

It's not surprising that graduates are asking the same question. Is it difficult to pass the Unified State Exam? The answer largely depends on your level of preparation. Some students prepare for the upcoming test with a tutor, while others prefer to study the material on their own.

Is it difficult for a student to pass the Unified State Exam?

As you know, a single exam can be taken as a final and entrance exam at the same time. Asking whether it is difficult to pass the Unified State Exam, applicants are simultaneously interested in how to get the highest score. Despite all the “horror stories” that claim that it is extremely difficult for an ordinary student to pass the exam successfully.

It’s only important to know how to prepare, and then you definitely shouldn’t be afraid.

Preparation for the Unified State Exam

You should never rule out the possibility of getting the highest score. Those students who start preparing in advance have the best chances. For example, systematically studying the school curriculum over several years will avoid the stress associated with the need to master a huge amount of material in a short time.

You can prepare yourself, take a special course, or contact a private teacher. To choose the appropriate option, you need to take into account how well the student knows the subject at the moment and how much time is left before the exam.

It is also important what subject you are taking.

Physics

Interestingly, this item is one of the four most popular. Physics is often chosen by schoolchildren. What is the reason for such popularity? After all, this subject cannot be called simple. The secret is that physics is needed for admission to technical universities. That's why boys take it much more often than girls.

Is it difficult to pass the Unified State Exam in Physics? As mentioned above, this subject is not one of the simple ones. Therefore, preparation should not only be lengthy, but also thorough.

The peculiarity of the Unified State Exam is that the student must not only have excellent knowledge, but also comply with the exam regulations. It is better to familiarize yourself with the rules in advance. For example, they are not allowed to bring into the classroom not only computer equipment, but also all sorts of new-fangled gadgets such as smart watches, etc. You are only allowed to take a ruler and a simple calculator.

When writing a test, you cannot exchange information with other students, it is also usually prohibited to leave without permission, etc.

Violation of requirements can lead to conflict.

To successfully pass physics, you need to score 36 points or more.

Social science

It is always difficult for schoolchildren to decide on their future profession. If a student does not imagine himself in either a humanities or a technical specialty, then social studies becomes a universal option. This subject will be useful for future psychologists, sociologists, economists and some other professions.

Is it difficult to pass the Unified State Exam in Social Studies? Some people mistakenly believe that this subject is simple because it does not involve memorizing complex formulas. However, this may be a mistake. Preparation cannot be neglected.

If a student assumes that when taking social studies he can indulge in philosophical reasoning and in this way successfully pass the exam, the result may disappoint him. The Unified State Exam format requires specific and clear answers.

That is why social studies requires knowledge of terminology, the ability to compare and analyze knowledge. This subject includes several humanitarian areas. Each of them opens up an abyss of knowledge with its own set of terms.

When choosing the Unified State Exam in social studies, you need to take the study of the subject seriously. This is the key to a successful result.

Biology

Not only schoolchildren, but also applicants have to take the Unified State Exam. Many people are incredibly afraid of this exam due to conflicting information. Therefore, the question of whether it is difficult to pass the Unified State Exam in biology remains a popular question.

There are probably no simple exams at all. Testing your knowledge is always stressful. According to experts, the greatest difficulty of the Unified State Exam in biology is that the exam covers a colossal layer of information. This science begins to be taught as a separate subject in grades 5-6.

Another difficulty is that biology includes many sections. For example, botany is studied in high school and knowledge may be forgotten by graduation. You will have to spend time re-learning the material.

When preparing for the Unified State Exam, you need to not only study the topics in the textbook. It is important to get used to the format in which the exam is administered. During the testing process, it is important to fill out the form correctly, without making mistakes. It will be a shame to receive a low score not because of a lack of knowledge, but because of errors in filling out.

Chemistry

This subject, unlike biology, begins to be taught in the 8th grade, so the amount of information is less. However, this does not mean that you can neglect preparation.

It is impossible to say for sure whether it is difficult to pass the Unified State Exam in biology and chemistry. Much depends on the current level. The more knowledge the student has acquired, the easier the preparation will be. It's worth starting with a check. It is recommended to pay the most attention to the most complex topics. This is where you need to start preparing for the Unified State Exam in Chemistry. After all, the more time you spend preparing, the better results you can achieve.

Having received 100 points on the final exam, yesterday's student will join the ranks of those who are regularly asked the question of

To pass the general chemistry exam, it is important to know the basics of the subject, be able to do math, use a calculator for more complex problems, and be willing to learn something new. Chemistry studies substances and their properties. Everything around us is related to chemistry, even the simplest things that we take for granted, such as the water we drink and the air we breathe. Be prepared to discover about everything around you. Getting to know chemistry will be exciting.

Steps

Good Study Habits

Meet the teacher or teacher. To pass the exam successfully, you should get to know the teacher and tell him what is difficult for you.

• Many teachers can be approached outside of class if students need help. In addition, they usually have methodological publications.

1. Gather a group for classes. Don't be ashamed that chemistry is hard for you. This subject is difficult for almost everyone.

   • When working in a group, people who can quickly understand a topic will explain it to others. Divide and conquer.

2. Read the required paragraphs in the textbook. A chemistry textbook isn't the most exciting read, but you should read the material carefully and highlight text that you don't understand. Make a list of questions and concepts that you find difficult to understand.

   • Come back to these parts later with a fresh mind. If you still find it difficult, discuss the topic in a group or ask your teacher for help.

3. Answer the questions after the paragraph. Even if there is a lot of material, you may have remembered more than you think. Try to answer the questions at the end of the chapter.

   • Sometimes textbooks have explanatory material at the end that describes the correct solution. This will help you understand where you made a mistake in your reasoning.

4. Study charts, images, and tables. Textbooks use visual ways to convey information.

   • Look at the pictures and diagrams. This will help you understand some concepts better.

5. Ask your teacher for permission to record the lecture. It is difficult to write down information and still look at the board, especially when it comes to such a difficult subject as chemistry.

   Review past exam questions. Sometimes students are given questions that have appeared in previous years' exams so that they can prepare better.

   • Don't memorize the answers. Chemistry is a subject where, in order to answer a question, it is important to understand what is being said, and not just repeat a memorized text.

6. Take advantage of online learning resources. Visit all the sites that the teacher recommends.

   Learn to identify the changes that occur during a chemical reaction. Chemical reactions begin with basic elements or compounds that react. As a result of the connection, a reaction product or several products are obtained.

   Learn different types of reactions. Chemical reactions can occur under the influence of various factors, and not just when elements combine.

   Use all available resources. You will need to understand the difference between the basic reactions. Use all possible materials to understand this difference. Don't be afraid to ask questions.

   • Understanding what changes during chemical reactions is not so easy. This will be one of the most challenging tasks in chemistry class.

7. Think about the reactions from a logical point of view. Try not to get confused by the terminology and make things even more complicated. All reactions are aimed at transforming something into something else.

   • For example, you already know what happens if you combine two hydrogen atoms and one oxygen atom - water. Therefore, if you pour water into a pan and put it on fire, something will change. You carried out a chemical reaction. If you put water in the refrigerator, a reaction will occur. You changed something that involved a substance involved in the reaction, which is water.
   • Go through each type of reaction until you understand everything. Focus on the source of energy that provokes the reaction and the major changes that result from the reaction.
   • If you find it difficult to understand this, make a list of unclear nuances and show it to your teacher, fellow students, or anyone who is well versed in chemistry.

Calculations

1. Know the sequence of basic calculations. In chemistry, very precise calculations are sometimes required, but a basic knowledge of mathematics is often sufficient. It is important to understand the sequence in which the calculations are carried out.

   • First, calculations are done in parentheses, then calculations in powers, then multiplication or division, and finally addition or subtraction.
   • In the example 3 + 2 x 6 = ___ the correct answer is 15.

2. Don't be afraid to round very long numbers. In chemistry, rounding is common because often the answer to an equation is a number with many digits. If the problem statement provides rounding instructions, take them into account.

   Understand what absolute value is. In chemistry, some numbers have an absolute value rather than a mathematical value. The absolute value is all values ​​up to a number from zero.

   Know all common units of measurement. Here are some examples.

   • The amount of a substance is measured in moles (mol).
   • Temperature is measured in degrees Fahrenheit (°F), Kelvin (°K), or Celsius (°C).
   • Mass is measured in grams (g), kilograms (kg) or milligrams (mg).
   • The volume of liquid is measured in liters (L) or milliliters (ml).

3. Practice converting values ​​from one measurement system to another. In the exam you will have to do such translations. You may need to convert temperatures from one system to another, pounds to kilograms, ounces to liters.

   • You may be asked to answer in units different from those in the problem statement. For example, in the text of the problem the temperature will be indicated in degrees Celsius, but the answer will be needed in degrees Kelvin.
   • Typically, the temperature of chemical reactions is measured in degrees Kelvin. Practice converting degrees Celsius to degrees Fahrenheit or Kelvin.

4. Do not hurry. Carefully read the text of the problem and learn how to convert units of measurement.

   Know how to calculate your concentration. Practice basic math by calculating percentages, ratios, and proportions.

   Practice with the nutritional information on food packages. To pass Chemistry, you need to be able to calculate ratios, proportions and percentages in different sequences. If this is difficult for you, start practicing using familiar units of measurement (for example, food packaging).

   • Get the nutrition facts package. You'll see calorie calculations per serving, percentage of recommended servings per day, total fat, percentage of calories from fat, total carbohydrates, and a breakdown by type of carbohydrate. Learn to calculate various ratios based on these values.
   • For example, calculate the amount of monounsaturated fat in total fat. Convert to percentage. Calculate how many calories are in a package by knowing the number of servings and the calorie content of each serving. Calculate how much sodium is in half the package.
   • This will help you easily convert chemical values ​​from one system to another, such as moles per liter, grams per mole, and so on.

5. Learn to use Avogadro's number. This number reflects the number of molecules, atoms or particles in one mole. Avogadro's constant is 6.022x1023.

   Think about carrots. If you're having trouble figuring out how to use Avogadro's number, try counting carrots instead of atoms, molecules, or particles. How many carrots are there in a dozen? We know that a dozen is 12, which means there are 12 carrots in one dozen.

   Understand molarity. Think about the number of moles of a substance contained in a liquid. It is very important to understand this example because we are talking about molarity, that is, the proportion of a substance expressed in moles per liter.

   Reduce the equations to an empirical formula. This means that the answer will only be correct if you reduce all the meanings to their simplest form.

   Know what is included in the molecular formula. The molecular formula does not need to be reduced to its simplest, or empirical, form, since it tells what exactly the molecule is made of.

   • The molecular formula is written using the abbreviations of the elements and the number of atoms of each element in the molecule.
   • For example, the molecular formula of water is H2O. This means that each water molecule contains two hydrogen atoms and one oxygen atom. The molecular formula of acetaminophen is C8H9NO2. Every chemical compound has a molecular formula.

6. Remember that the mathematics in chemistry is called stoichiometry. You will come across this term. This is a description of how chemistry is expressed in mathematical formulas. In chemical mathematics, or stoichiometry, quantities of elements and chemical compounds are often expressed in moles, moles, moles per liter, or moles per kilogram.

   Ask for additional assignments. If you have trouble with equations and conversions, talk to your teacher. Ask to be given more tasks so that you can work on them yourself until the essence of all phenomena becomes clear to you.

The language of chemistry

Learn to understand Lewis diagrams. Lewis diagrams are sometimes called scatter plots. These are simple diagrams in which dots represent free and bound electrons in the outer shell of an atom

Find out what the octet rule is. Lewis diagrams use the octet rule, which states that an atom becomes stable when it has access to eight electrons in its outer shell. Hydrogen is an exception - it is considered stable if it has two electrons in its outer shell.

Draw a Lewis diagram. The letter symbol of an element surrounded by dots is a Lewis diagram. Think of the diagram as a movie frame. Electrons do not rotate around the outer shell of the elements - they are reflected in a certain period of time.

1. Understand how electrons bind elements together. Lewis diagrams represent chemical bonds in a simple form.

   • Discuss this topic with your teacher and classmates if you are unclear about how elements are connected and what Lewis diagrams represent.

There is hardly a final exam more difficult than the OGE or the Unified State Exam in chemistry. This subject must be taken by future biologists, chemists, doctors, engineers and builders. Today we will talk about what you need to know in order to get high scores, and what benefits are best to use.

Books and manuals for preparation

Unified State Examination and Unified State Examination experts recommend relying on specialized-level textbooks when preparing. The material in a standard basic textbook is not enough to successfully pass the exam. Practice shows that schoolchildren who have taken a specialized chemistry course feel quite confident during the exam. Several such textbooks have been written, but in terms of content and presentation they are approximately the same.

We recommend getting a collection of standard exam tasks - the official publication of FIPI (with a hologram) and a couple of books by other authors. They analyze tasks in detail, show ways to solve them, and provide algorithms and answers for self-control. The more options you solve, the greater your chances of passing the exam.

Repetition is the mother of learning

This is an important component of quality training. Chemistry is a complex science about matter; without knowing the basic topics of the initial course, you will not understand more complex ones. Of course, there may not be enough time to repeat the entire program, so it is better to pay more attention to precisely those issues that cause the most difficulty.

According to teachers at the Merlin Center, schoolchildren more often make mistakes in assignments related to the following topics:

• mechanisms of molecular bond formation;
• hydrogen bond;
• patterns of chemical reactions;
• physicochemical properties of solutions, electrolytic dissociation, reactions in electrolyte solutions;
• the effect of solution dilution on the degree of dissociation (Ostwald's dilution law);
• hydrolysis of salts;
• atmospheric compounds;
• main classes of compounds;
• industrial production and scope.

The same standard exam tasks and tests will help you identify gaps. Does not work? Ask your chemistry teacher for help or sign up for prep courses.

Conduct experiments

Chemistry is a science based on real experiments with substances. Experiments will help you better understand a particular topic. To do this, it is not necessary to buy a set of reagents and laboratory supplies. There are many interesting, well-produced videos on the Internet about chemical reactions. Don't be lazy to find them and look.

Be careful during the exam!

Most mistakes are made by children precisely because of inattention. Train yourself not to miss a single word when reading the task, pay attention to the wording and how many answers there should be.

• Read the question to the end, think about its meaning. There is often a little clue hidden in the wording.
• Start with easy questions where you have no doubt about the correctness of the answers, then move on to more complex tasks where you need to think.
• If a question is too difficult, skip it, don't waste time, you can come back to it later.
• The tasks are not related to each other, so focus only on the one you are doing at the moment.
• If you have difficulty, first try to eliminate obviously incorrect answers. It’s easier to choose an option from the remaining two or three than to get confused among five or six answers.
• Be sure to leave time to check your work so that you can quickly review assignments and correct any mistakes. An unfinished word or number may cost you a point.

Chemistry is a difficult subject, and it is best to prepare for the exam under the guidance of an experienced teacher; it is not recommended to count on the fact that you will cope with such an important task. Only a teacher can point out “inconspicuous” mistakes and help you fill in the gaps and explain complex material in simple, accessible language.
