OGE variant chemistry past years. Collection of ideal social studies essays

The Unified State Examination in Chemistry is an exam that graduates who plan to enter a university for certain specialties related to this discipline take. Chemistry not included compulsory subjects According to statistics, out of 10 graduates, 1 passes chemistry.

• For testing and completing all tasks, the graduate receives 3 hours of time - planning and allocating time to work with all tasks is important task subject.
• Usually the exam includes 35-40 tasks, which are divided into 2 logical blocks.
• Like the rest of the exam, the test in chemistry is divided into 2 logical blocks: testing (choosing the correct option or options from those offered) and questions that require detailed answers. It is the second block that usually takes longer, so the subject needs to rationally allocate time.

• The main thing is to have reliable, deep theoretical knowledge, which will help to successfully complete various tasks of the first and second blocks.
• You need to start preparing in advance in order to systematically work through all the topics - six months may not be enough. The best option is to start training as early as the 10th grade.
• Identify the topics that are most problematic for you so that when you ask your teacher or tutor for help, you know what to ask.
• Learning to perform tasks typical for the Unified State Examination in Chemistry is not enough to master the theory, it is necessary to bring the skills of performing tasks and various tasks to automatism.
  

• Not always self-training effective, so it is worth finding a specialist to whom you can turn for help. The best option is a professional tutor. Also, don't be afraid to ask questions. school teacher. Don't neglect school education Please do your homework carefully!
• Exam tips! The main thing is to learn how to use these sources of information. The student has a periodic table, tables of metal stress and solubility - this is about 70% of the data that will help to understand various tasks.

• Chemistry requires a solid knowledge of mathematics - without this it will be difficult to solve problems. Be sure to repeat the work with percentages and proportions.
• Learn the formulas that are needed to solve problems in chemistry.
• Study the theory: textbooks, reference books, collections of tasks will come in handy.
• The best way to fix theoretical tasks- Actively solve tasks in chemistry. AT online mode you can solve in any number, improve your problem solving skills different type and difficulty level.
• Controversial points in assignments and errors are recommended to be disassembled and analyzed with the help of a teacher or tutor.

Part 1 contains 19 short answer tasks, including 15 tasks basic level difficulties ( sequence numbers of these tasks: 1, 2, 3, 4, ...15) and 4 tasks advanced level complexity (the serial numbers of these tasks: 16, 17, 18, 19). For all their differences, the tasks of this part are similar in that the answer to each of them is written briefly in the form of one digit or a sequence of digits (two or three). The sequence of numbers is written in the answer sheet without spaces and other additional characters.

Part 2, depending on the CMM model, contains 3 or 4 tasks high level complexity, with a detailed answer. The difference between examination models 1 and 2 is in the content and approaches to completing the last tasks of the examination options:

Exam Model 1 contains task 22, which involves performing a "thought experiment";

Exam model 2 contains tasks 22 and 23, which provide for the execution laboratory work(real chemical experiment).

Scale for converting points into grades:

"2"– from 0 to 8

"3"– from 9 to 17

"4"– from 18 to 26

"5"– from 27 to 34

The system for assessing the performance of individual tasks and the examination work as a whole

The correct performance of each of the tasks 1-15 is estimated at 1 point. The correct performance of each of the tasks 16-19 is estimated as a maximum of 2 points. Tasks 16 and 17 are considered completed correctly if two answers are correctly selected in each of them. For an incomplete answer - one of the two answers is correctly named or three answers are named, of which two are correct - 1 point is given. The rest of the answers are considered incorrect and are scored 0 points. Tasks 18 and 19 are considered completed correctly if three matches are correctly established. Partially correct is the answer in which two out of three matches are established; it is worth 1 point. The remaining options are considered incorrect answers and are scored 0 points.

Checking the tasks of part 2 (20–23) is carried out by the subject commission. Maximum score for a correctly completed task: for tasks 20 and 21 - 3 points each; in model 1 for task 22 - 5 points; in model 2 for task 22 - 4 points, for task 23 - 5 points.

To complete the examination work in accordance with model 1, 120 minutes are allotted; according to model 2 – 140 minutes

Tips for preparing for the exam in chemistry on the site site

How to correctly pass the exam (and OGE) in chemistry? If the time is only 2 months, and you are not ready yet? Yes, and do not be friends with chemistry ...

It offers tests with answers for each topic and task, passing which you can learn the basic principles, patterns and theory found in the exam in chemistry. Our tests allow you to find answers to most questions found in the exam in chemistry, and our tests allow you to consolidate the material, find weak spots and work out the material.

All you need is the Internet, stationery, time and a website. It is best to have a separate notebook for formulas / solutions / notes and a dictionary of trivial names of compounds.

1. From the very beginning, you need to assess your current level and the number of points that you need, for this you should pass. If everything is very bad, but you need excellent performance, congratulations, even now all is not lost. Target yourself on successful delivery You can do it without the help of a tutor.
   Decide on the minimum amount points you want to score, this will allow you to understand how many tasks you must solve exactly in order to get the score you need.
   Naturally, keep in mind that things may not go so smoothly and decide how you can more tasks, but better for everything. The minimum that you have determined for yourself - you must decide ideally.
2. Let's move on to the practical part - training for the solution.
   Most effective method- next. Choose only the exam you are interested in and solve the corresponding test. About 20 solved tasks guarantee a meeting of all types of tasks. As soon as you begin to feel that you know how to solve every task you see from beginning to end, proceed to the next task. If you do not know how to solve any task, use the search on our site. There is almost always a solution on our website, otherwise just write to the tutor by clicking on the icon in the lower left corner - it's free.
3. In parallel, we repeat the third paragraph for everyone on our site, starting with.
4. When the first part is given to you at least at an intermediate level, you begin to decide. If one of the tasks does not lend itself well, and you made a mistake in its implementation, then you return to the tests for this task or the corresponding topic with tests.
5. Part 2. If you have a tutor, focus on learning this part with him. (assuming you are able to solve the rest at least 70%). If you started part 2, then you should gain a passing score without any problems in 100% of cases. If this does not happen, it is better to stay on the first part for now. When you are ready for part 2, we recommend that you get a separate notebook where you will write down only the solutions of part 2. The key to success is solving as many tasks as possible, just like in part 1.

Who are these tests for?

These materials are intended for students preparing for OGE-2018 in chemistry. They can also be used for self-monitoring when studying school course chemistry. Each is dedicated to a specific topic that a ninth grader will meet on the exam. The test number is the number of the corresponding task in the OGE form.

How are thematic tests arranged?

Will other thematic tests be published on this site?

Undoubtedly! I plan to place tests on 23 topics, 10 tasks each. Stay tuned!

What else is on this site for those preparing for the OGE-2018 in chemistry?

Do you feel like something is missing? Would you like to expand some sections? Need some new content? Something needs to be corrected? Did you find any mistakes?

Good luck to everyone preparing for the OGE and the USE!
