Is it difficult to pass the exam in chemistry?  Is it difficult to take the exam in chemistry? You need to know to pass the exam in chemistry

No wonder graduates ask the same question. Is it difficult to pass the exam? The answer largely depends on the level of training. Some students are preparing for the upcoming test with a tutor, some prefer to study the material on their own.

Is it difficult for a student to pass the exam?

As is known, single exam You can take both graduation and entrance exams at the same time. Asking the question of whether it is difficult to pass the exam, applicants are simultaneously interested in how to get the highest score. Despite all the "horror stories" that assure that it is extremely difficult for an ordinary student to successfully pass the wrong test.

It is only important to know how to prepare, and then you definitely should not be afraid.

Preparation for the exam

You should never rule out the possibility of getting the highest score. Those students who start preparation in advance have the most chances. For example, a systematic study of the school curriculum for several years will help to avoid the stress associated with the need to master a huge amount of material in a short time.

You can prepare yourself, become a student of special courses or contact a private teacher. To choose the appropriate option, you need to consider how well the student knows the subject at the current moment and how much time is left before the exam.

It is also important what subject to take.

Physics

It is curious that this item is among the four most popular. It is physics that is often chosen by schoolchildren. What is the reason for such popularity? After all, this subject can not be called simple. The secret is that physics is needed for admission to technical universities. That is why boys pass it much more often than girls.

Is it difficult to pass the exam in physics? As mentioned above, this subject is not among the simple ones. Therefore, preparation should be not only lengthy, but also thorough.

Feature of the exam is that the student must not only have brilliant knowledge, but also comply with the rules of the exam. It is better to familiarize yourself with the rules in advance. For example, they are not allowed to bring not only computer equipment into the audience, but also all sorts of newfangled gadgets like smart watches, etc. It is allowed to take only a ruler and a simple calculator.

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

Violation of the requirements can lead to conflict.

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

Social science

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

Is it difficult to pass the exam in social studies? Some mistakenly believe that this subject is simple, since it does not involve memorizing complex formulas. However, this may be a mistake. Preparation cannot be neglected.

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

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

When choosing the exam in social studies, you need to take the study of the subject seriously. This is the key to a successful outcome.

Biology

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

Probably, there are no simple exams at all. Checking knowledge is always stressful. According to experts, the greatest difficulty of the exam in biology is that the exam covers a colossal layer of information. As a separate subject, this science begins to be taught in grades 5-6.

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

When preparing for the exam, you need not only to study the topics of the textbook. It is important to get used to the format in which the exam is conducted. During the testing process, it is important to fill out the form correctly without making mistakes. It will be a shame to get 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 preparation can be neglected.

It is impossible to say unequivocally whether it is difficult to pass the exam in biology and chemistry. Much depends on the current level. The more knowledge the student has mastered, the easier it will be to prepare. It's worth starting with a check. The greatest attention is recommended to be paid to the most difficult topics. It is with them that you need to start preparing for the exam in chemistry. After all, the more time for preparation, the better results can be achieved.

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


I'll start with a short introduction for the purpose of parting speech for those who are just facing such a life test as the Unified State Examination😲

Now the one who reads this, getting used to reading the stories of 100-pointers, thinks something like: “why are there so few points ???”. Believe me, once I also read here the stories of people with not very high scores and thought “well, I’ll definitely pass better” 😂😂😂 But when I myself came face to face with exams, my opinion about the exam and the scores completely turned upside down , and about those people who wrote their surrender stories in this group.

Let's start with the fact that I studied well all my conscious life and I never had threes and twos ("yes she is a nerd" - you might think, but I personally do not consider myself a nerd, since good grades, in most cases, are not the result of knowledge is only an indicator of how you can get out in a certain situation, i.e. cheat somewhere, consult classmates somewhere, for example, make one of them solve math for you😂, etc.) .To be honest, in the 10th and 11th grades, I generally scored on grades and prepared only for those subjects that I had to take.

I tried to start preparing in the 10th grade, but I didn’t really succeed 🤣 And at the beginning of the 11th grade, my laziness and the feeling that there was still a lot of time ahead didn’t let me sit down and start preparing for the exam (I just slowly started reading biology, and even more because I am madly in love with this subject and it is very interesting to me even without the exam).

Math base - 20/20 score 5

The only one exam, for which I didn’t prepare at all, and before they gave me kim, I didn’t see the tasks from the matan, because I simply didn’t give a damn what I would pass, because you yourself know that this exam does not play any role at all.

How to become an expert?

I advise you not to waste time and not solve a single option, since without it you can write on 5)

Chemistry - 78

It was my favorite subject until the 10th grade, until the organics started🤣 The organics seemed wildly complex to me before I came to the 11th grade and didn’t go crazy with the sooooo complex inorganics, many of the usual reactions from which were replaced with some kind of tin, which I I didn’t see it in my eyes😂 And only in the 11th grade you begin to understand that organic matter is actually easy, compared to inorganic matter). For those who have difficulties with organics, now I will give the most important advice: DO NOT CREMEN ORGANICS, STUPIDLY SIT ASS ON A CHAIR AND SOLVE TO FOAM FROM THE MOUTH OF THE CHAIN, after solving about 100-200 chains, you will come to the realization that all reactions in organics are repeated and that in the process of resolving they themselves are remembered)

I have been preparing since March according to everyone's favorite FIPI collection and according to Doronkin's collection “Tasks high level complexity ”(and in general, solve as many Doronkin’s collections as possible, since very often the same tasks come across in the exam in terms of complexity). I don’t advise the exam at all, since the site has become obsolete, and they post left-handed assignments that are not even mentioned in the exam😣 I studied without a tutor and if I didn’t make stupid mistakes due to inattention, I could easily get about 80- 90 points). But if you need 100, then only a tutor will help you). If about the exam itself, then this year the second part was much easier than the first, which was noticed not only by me, but also by all my classmates). Most importantly, prepare well in advance for the second part, because in the process of preparation you will prepare for the first part). Screenshots of the second part will be given below and you will see that everything was very easy in part 2)))

Russian language - 85

I had the same preparation for this subject as for basic mathematics, i.e. NO 🤣For two years I have not solved a single test and have not written a single essay. To be honest, 2 days before the exam, I just figured out the structure of the essay and read the cliches. And with an empty head I went to the exam, relying only on my luck and love of reading😂 And, oddly enough, I was lucky, I got a light text on the problem of manifestation of maternal love))) it’s impossible to write Russian for a high score without any preparation at all, it turns out that EVERYTHING is POSSIBLE))) It’s a shame, of course, that they took off points for speech and language norms, it could have been about 90-95 points (But I’m still happy with the result, since many people who prepared hard for two years, who spent their time writing compositions, received the same points as me, who did not prepare at all).

* HERE NOW THERE WILL BE A LITTLE BAD ADVICE, BUT I HAVE A REQUEST TO FUTURE GRADUATES: DO NOT PREPARE FOR SUCH SUBJECTS LIKE MATHEMATICS BASIC AND RUSSIAN, SINCE YOU WILL PASS THESE EXAMS WITHOUT SPECIAL WORK (if you are an adequate person and know how to write 😂) SPEND YOUR TIME FOR PROFILE SUBJECTS, AS EVERY YEAR THEY MAKE THEM HARDER AND HARDER.

Biology-74

Worst Exam and Result!!! Biology is my favorite subject, I like to read books on biology even in my free time, and this is the subject in which I have three exams lowest score!! THIS IS A CLEAR PROOF THAT THE USE ABSOLUTELY DOES NOT SHOW KNOWLEDGE, YOU can read at least a hundred books, be a professor of biology, but this does not mean absolutely anything, since the exam in biology is just plain luck (((I just got the most difficult option, with questions in 2 parts that can only be answered by people who have been working for a long time in a certain industry, i.e. questions that do not relate to the school curriculum at all.I came out of this exam in absolute bewilderment, because I did not expect such In this case, I advise you to read university-level books as much as possible (not from the school curriculum), draw up notes for yourself on the entire school curriculum so that at the end of the year they fly off the teeth, you can solve the collection of FIPI Rokhlova, but I would advise you to do this lastly, since I personally didn’t really like it, because it has a lot of biological errors and exam assignments(even test ones) are much more difficult than the level of these collections.

To succeed in the general chemistry exam, it is important to know the basics of the subject, be able to count, use a calculator for more complex problems, and be ready to learn something new. Chemistry is the study of substances and their properties. Everything around us is linked to chemistry, even the simplest things we take for granted, such as the water we drink and the air we breathe. Get ready to discover about everything that surrounds you. Getting to know chemistry will be exciting.

Steps

Good study habits

    Get to know the teacher or teacher. To successfully pass the exam, 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 to practice. Don't be ashamed that chemistry is hard for you. This subject is difficult for almost everyone.

    • Working in a group, people who can quickly understand a topic will explain it to others. Divide and conquer.
  2. Read the relevant paragraphs in the textbook. A chemistry textbook is not the most exciting reading, but you should carefully read the material and highlight the text that you do not understand. Make a list of questions and concepts that you find difficult to understand.

    • Come back to these parts later with a fresh head. 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 remember more than you think. Try to answer the questions at the end of the chapter.

    • Sometimes tutorials have explanatory material at the end that describes the correct solution. This will help you understand where you made a mistake in reasoning.
  4. Explore charts, images, and tables. Textbooks use visual methods to convey information.

    • Look at the pictures and diagrams. This will help you better understand some of the concepts.
  5. Ask your teacher for permission to record the lecture on a voice recorder. It is difficult to write down information and look at the blackboard at the same time, especially when it comes to such a difficult subject as chemistry.

    Check out previous exam questions. Sometimes students are given questions that have been used in exams in previous years so that they can better prepare.

    • 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 the memorized text.
  6. Take advantage of online learning resources. Visit all sites recommended by the instructor.

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

    Learn different types of reactions. Chemical reactions can occur under the influence of various factors, and not only when elements are combined.

    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 in chemical reactions is not easy. This will be one of the most difficult tasks in the chemistry class.
  7. Think of reactions in terms of logic. Try not to get confused in the terminology and not make everything even more complicated. All reactions are aimed at turning 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 pot and put it on fire, something will change. You performed 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. Concentrate on the energy source that triggers the reaction and the major changes that result from the reaction.
    • If you find it difficult to understand, make a list of obscure nuances and show it to the teacher, fellow students, or anyone who is well versed in chemistry.

Calculations

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

    • First, calculations are done in brackets, then calculations in powers, then multiplication or division, and finally addition or subtraction.
    • In the example 3 + 2 x 6 = ___, the correct answer would be 15.
  2. Don't be afraid to round very long numbers. Rounding is often used in chemistry because often the answer to an equation is a number with many digits. If there are instructions for rounding in the problem statement, take them into account.

    Understand what absolute value is. In chemistry, some numbers have an absolute value, not a mathematical one. The absolute value is all values ​​up to a number from zero.

    Know all common units of measure. 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 deal with such translations. You may need to convert temperature from one system to another, pounds to kilograms, ounces to liters.

    • You may be asked to answer in units other than those in the problem statement. For example, in the text of the problem, the temperature will be indicated in degrees Celsius, and the answer will be needed in degrees Kelvin.
    • Usually the temperature of chemical reactions is measured in degrees Kelvin. Practice converting Celsius to Fahrenheit or Kelvin.
  4. Do not hurry. Read the text of the problem carefully and learn how to translate units of measurement.

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

    Practice on 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 training in familiar units of measurement (for example, on food packaging).

    • Take the package with the nutritional information. You'll see a calculation of calories per serving, the recommended serving per day percentage, total fat, percentage of calories from fat, total carbs, and a breakdown by carb type. Learn to calculate different 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 a 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 carrots. If you're having trouble understanding how to use Avogadro's number, try counting carrots instead of atoms, molecules, or particles. How many carrots are in a dozen? We know that a dozen is 12, so there are 12 carrots in one dozen.

    Understand molarity. Think about the number of moles of a substance in a liquid. It is very important to understand this example because it is 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 values ​​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, because it tells you exactly what 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 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, the amounts of elements and chemical compounds are often expressed in terms of moles, percentages in moles, moles per liter, or moles per kilogram.

    Ask for extra assignments. If equations and conversions are hard for you, talk to your teacher. Ask them to give you more problems 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 charts. Lewis charts are sometimes called scatter plots. These are simple diagrams in which dots represent free and bound electrons in the outer shell of an atom.

    Learn what the octet rule is. Lewis diagramming uses 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 in the presence of two electrons in the outer shell.

There are 35 tasks in the exam in chemistry. Of these, 29 - with a short answer and 6 tasks with a detailed answer.

1 point

Tasks 1-6, 11-15, 19-21 and 26-29. The task is considered completed if the correct answer is given in the form of a sequence of numbers or a number with a given degree of accuracy.

2 points

Tasks 7-10, 16-18 and 22-25. The task is considered completed correctly if the sequence of numbers is correctly indicated. 1 point is deducted for one mistake. If there is more than one error or there is no answer, 0 points are given.

2-5 points

Solving problems with a detailed answer - provided that the task is completed completely and correctly in accordance with the evaluation criteria. Here it is necessary to correctly formulate the solution to the problem and prescribe the entire sequence of actions so that the examiner is clear how and why you came to the solution.

Exam preparation

What you should pay attention to:

- Be sure to study the codifier and specification for the exam in chemistry, posted on the FIPI website. It contains all the topics that you need to know, the number of points for solving each task and the assessment criteria.

- Use caution when preparing USE options previous years. They contain many errors and inconsistencies.

— Demo version The exam is always easier than the one that will be on the exam. It reflects only the topics and format of assignments.

— In order to feel confident in the exam, it is necessary to solve complex problems, for example, tasks for students. Then the exam will not cause you any difficulties.

- When preparing for the exam, do not get hung up on one author. All textbook authors have favorite topics and problem formats. The more tasks from different textbooks you solve, the easier it will be for you on the exam.

- To write the exam at a good level, you need to know not only the basic principles and laws that we use when writing a chemical reaction or when we talk about the properties of compounds. You need to be good with exceptions. There are a lot of exceptions in chemistry that you just need to learn and not miss out of inattention when solving a problem.

Organizational moments

You have 3.5 hours to complete the tasks. With good preparation, three hours to complete all tasks is enough. You will have 30 minutes to double-check everything.

Be sure to bring a watch with you and keep track of the time. The clock in the auditorium may not be accurate. Hours should be the most common. Mobile phones and smart watches are not allowed on the exam. You can be removed from the exam even if your mobile phone is turned off, so don't risk it.

It is allowed to use a calculator on the exam, including engineering. The main thing is that it is not programmable. Just in case, take two calculators with you: an engineering one and a regular one. If the engineering calculator is still taken away, you will not have to count in a column, wasting time. Start using the calculator while preparing for the exam to get used to it and not make mistakes when pressing the keys.

On the exam, you can use the periodic system of Mendeleev, a table of solubilities of salts, acids and bases in water, as well as an electrochemical series of metal voltages. Download these materials in advance and practice using them. The periodic table on the exam is different from the school tables, painted in different colors.

Periodic system of chemical elements D.I. Mendeleev

Solubility of acids, salts and bases in water and the electrochemical series of voltages of metals

Set aside at least an hour to transfer the completed work to a clean copy. When checking and USE assessment drafts are not counted.

The results of the first part of the exam in chemistry are not revised. But the results of the second part can be reviewed if you file an appeal. As a result of the appeal, you can add points. Cases when points are removed after an appeal are very rare, so if you are sure that you have decided correctly, feel free to apply. If in doubt - consult a teacher or senior comrades, well those who know chemistry.

✔️ Carefully read the condition of the problem and write down the numbers of the selected options in exactly the sequence that is required of you. Otherwise, the score for the task will not be counted, even if the option numbers are chosen correctly.

✔️ Acids in chemistry are divided into strong, medium and weak. However, strong acids are isolated on the exam, and all the rest are considered to be weak. Keep this in mind when solving problems.

✔️ Completing tasks for no organic chemistry, you need to know not only how each class of elements interacts, but also what reactions each element enters into. Each element has its own characteristics that need to be learned.

✔️ Always check all the options that are offered to you. Even if you think you've found the right one, you may be wrong. If you've ruled out all options, don't choose the last "default" one, decide that too. Make sure it's correct.

When writing reactions, do not forget to equalize all elements. With the help of oxygen, you can check if you have called everything correctly. If the oxygen converged, then everything is correct, if not, look for an error.

✔️ In tasks with a detailed answer, there can be only one correct answer, and maybe several. If you see two ways to solve a problem, choose the one you have the least doubt about.

✔️ If you need to write one answer, and you see several, proceed in the same way - write one option that you are sure of.

✔️ In problems with a detailed answer, always write "given". This will not add points to you, but it will help you calm down, streamline the condition of the problem and figure out what is required of you.

✔️ If you don't know the answer to a short answer task, skip it and come back to it after completing all the tasks, including the long answer tasks. Think again what should be there, and give an answer.

Use not only knowledge of chemistry, but also logic.

Is it difficult to pass the exam in chemistry and biology in the 11th grade?? and got the best answer

Answer from Glyana Obruch[newbie]
I sold them last year. If you understand these subjects, then everything is quite simple.
There are three parts to the exam in biology. The first one is pretty easy. When choosing one of the 4 answers, half is immediately swept aside, and between the remaining two you will need to think a little)
In the second part there will be correspondences (connect the first and second columns in pairs), the distribution of words into groups (for example, which signs relate to reptiles, which to amphibians) and other similar tasks. I the third part consists of questions that will need to be answered. There may also be tasks for cytology and genetics. I strongly advise you to repeat their decisions, since I myself got a little confused in genetics during the exam)
The structure of exams in chemistry is similar to biology. Only in the third part, the questions do not need to be answered. There will be tasks to be solved. And the task, I confess, is not easy. It would be nice to repeat the redox equations. Oh yes! And almost half of the tasks in the entire exam are based on organic chemistry. If you're good at it, you'll pass for sure)
Good luck with exams!)
