Tests in computer science exam with an explanation. Proper preparation for the exam in computer science from scratch

USE in Informatics Grade 11

The purpose of the Unified State Examination in Informatics is to assess the general education in computer science of graduates of XI (XII) classes educational institutions and applicants for the purpose of selection for enrollment in institutions of higher professional education.

Task structure

Exam options consist of 27 tasks of varying complexity (basic, advanced, high), divided into two parts.

Part 1 consists of 23 short answer questions. Of these, 12 tasks belong to the basic level of knowledge, 10 - to the advanced level, and one - to the high level. The answer to the tasks of the first part is written in the form of a sequence of numbers and letters in two places: in the answer field in the text of KIMs and in the corresponding line of the answer form No. 1.

Part 2 is four tasks for a detailed solution (one question advanced level and three - high). Solutions of 24-27 tasks are recorded in full on the answer sheet No. 2. If necessary, an additional sheet is drawn up.

Additional Information

The USE in Informatics 2016 is one of the longest. It lasts almost 4 hours (235 minutes). It is strictly forbidden to use additional materials and equipment during the Informatics and ICT exam. KIMs are designed in such a way that there is no need to use calculators. The graduate will have to answer questions and model the program; there are no complex computational tasks involving the use of technology.

Passing scores for the Unified State Examination in Informatics and ICT

The passing level is fixed in the region of 8 primary points. To do this, it is enough to correctly solve eight tasks from the first part. The score conversion scale determined that this corresponds to 40 secondary scores.

At present, there is a growing interest in the exact sciences in general and in computer science in particular. And many universities provide services for the training of professionals related to this particular subject. Therefore, the average score with which you can really enter a university is determined at the level of 70-80. Moreover, the competition can be traced even to paid places.

Preparation for the exam in computer science

From successful delivery exams in grade 11 depends on the fate of the graduate, his future, his profession. Therefore, great attention should be paid to the preparation for this stage. Preparation for the exam in computer science in 2016 should begin with the study of relevant literature, which includes school textbooks and additional manuals. After getting acquainted with the theory, it is necessary to master the skills of solving problems, adapt to the wording and requirements of the exam.

This will help the Collection of tasks in computer science of the Unified State Examination 2016 under the guidance of E.M. Zorina and M.V. Zorin. Issue includes assignments different types for all USE topics(+ answers to them) and guidelines.

You can also use collections of typical tasks from other authors.

For example: Informatics. Thematic test USE assignments in informatics. Krylov S.S., Ushakov D.M. or computer science. The most complete edition standard options assignments. Ushakov D.M., Yakushkin A.P. These collections were published in 2014, but the structure of the computer science exam has changed slightly, which allows the use of these sources.

Online learning

For thorough preparation for the exam federal Service for Supervision in the Sphere of Education and Science has created a website with an open bank of tasks. This resource contains information related to the exam: regulations, demos, manuals, specifications, codifiers. The FIPI open bank (fipi.ru) allows you to find your " weak spots”and work them out, pulling up both theory and practice. Additionally, a meeting room is organized on the site to ask questions that in one way or another relate to the exam.

The purpose of the demo is to enable USE participants to get acquainted with the structure of the future exam, with the number and wording of tasks, here are the answers to them and an analysis of the evaluation criteria.

To assess the quality of preparation of schoolchildren for the upcoming exams, online tests and mock exams are organized. An online test is a real-time examination on the Internet. After passing, you can see your results, as well as parse the correct answers. Online testing can also be used as a method of self-control after studying a specific topic.

What is important to know before choosing a computer science exam

1. The exam has a specialized level. This means that if in your school in grades 10-11 computer science is once or twice a week, then this number of hours will be clearly not enough for preparation.

The good thing is that you can prepare yourself. There are a lot of resources on the Internet for self-study with disassembled tasks, explanations and examples. As an example, I will cite the site of the remarkable St. Petersburg scientist and teacher Konstantin Yuryevich Polyakov (this site is known to everyone in our narrow circles).

2. The exam contains many pitfalls and "chips"; if you know about them in advance, some tasks will click like nuts. If you are seven spans in your forehead and have not spent much time on preparation, relying on luck and your own high IQ, you are at great risk of stumbling on some tasks. Spend more time than you need and risk not doing all the volume that was originally planned.

3. There are a lot of programming tasks in the exam. The only way to learn how to solve these problems is to learn how to program. Just resolving typical tasks programming will not work. It is important to learn how to solve problems yourself in order to understand how programs work, to recognize the basic blocks and to learn how to quickly determine what exactly a particular program “does”.

4. If you stubbornly want to take computer science, but do not know how to program, program in the Kumir algorithmic language. It is much simpler than other languages and allows you to concentrate on solving the problem, and not on where to put the semicolon correctly. Link and educational materials for its study is also on Polyakov's website.

5. If you don't do well in math, you won't do well in computer science either. These are two related items. If you are friends with mathematics, everything will work out with computer science too.

6. Do not try to prepare for the exam using textbooks. Will not work. Only Internet resources, video tutorials on YuoTube and good teacher at school.

Lada Esakova

When a student of grade 11 begins to prepare for the exam in computer science, as a rule, he prepares from scratch. This is one of the differences between the exam in computer science and exams in other subjects.

In mathematics, the knowledge of a high school student is definitely not zero. In Russian, even more so.

But in computer science, the situation is much more complicated. What is studied at school in the classroom has nothing to do with the preparation program for the exam in computer science.

What is the USE in Informatics?

Control USE test in computer science contains 27 tasks, which are among the most different topics. These are number systems, this is Boolean algebra, algorithmics, this is programming, modeling, elements of graph theory.

The USE in Informatics covers a very wide range of information. Of course, the exam will only need the basics, but these are the basics of important and modern topics.

Preparing for the Unified State Exam in computer science from scratch implies that the student did not study any of these topics at school. Usually it is!

For example, such a topic as Boolean algebra, or the algebra of logic, is included in the exam in computer science. But it is not studied in schools, even in specialized ones. She is neither in the course of school computer science, nor in the course of mathematics. The student has no idea!

And therefore, almost none of the students solves the famous problem on systems of logical equations. This problem in the Unified State Examination in Informatics is number 23. Let's say more - teachers often recommend that high school students not try to solve this problem at all, and not even look at it, so as not to waste time.

Does this mean that task 23 from the Unified State Examination in Informatics is not solved at all? Of course not! Our students regularly solve it every year. In our course of preparation for the Unified State Examination in Informatics, from many topics, we take only what is required for the exam. And we pay maximum attention to these tasks.

Why does the school not prepare for the exam in computer science?

This is due to the fact that computer science is not a compulsory subject. The Ministry of Education does not provide any standards and programs. Therefore, teachers at computer science lessons give students completely different material- who can. Moreover, in some schools there are no computer science lessons at all.

What do high school students usually do in computer science classes? Do they play shooting games?

Fortunately, at school, in computer science lessons, schoolchildren are still engaged not in nonsense, but quite useful things. For example, they study Word and Escel. This will come in handy in life, but, unfortunately, for passing the exam- absolutely useless.

Moreover, the guys study Word at a serious level, and some even pass exams in computer layout and receive a certificate of a typesetter. Some schools teach 3D modeling. A lot of schools give web design. This is a wonderful topic, useful in the future, but it has absolutely nothing to do with the exam! And coming to our courses, the student really prepares for the exam in computer science from scratch.

A similar situation is with high school students of specialized lyceums. Strong profile lyceums honestly teach programming in computer science lessons. The guys come out of there as good programmers. But after all, in the USE in computer science, only 5 tasks are somehow related to programming, and of them exactly one task in the USE version is devoted to writing a program! The result is a maximum of 6 tasks for the exam in computer science.

How much time does it take to prepare for the exam in computer science from scratch?

There is good news! You can prepare for the exam in computer science from scratch in one year. It's not easy, but it's possible, and our students prove it every year. The course of preparation for the exam in computer science is not very large. You can take courses once a week for 2 hours. Of course, you need to actively do your homework.

But there is one amendment. If a student has never done programming before grade 11, it is hardly possible to fully master programming in a year. Therefore, problem No. 27 will remain unsolved version of the exam in informatics. She is the most difficult.

It is especially difficult to prepare for the exam in computer science from scratch for those students who have never been familiar with programming at all and do not know what it is. This area is quite specific, so programming training needs to be given a lot of time and solve a huge number of tasks.

In our courses, we make sure to analyze all the typical programming tasks. And not once during the exam did the programming problem come as a surprise to our students - they were all sorted out during the courses. And only task 27 is left out for those who did not do programming at all until the 11th grade.

Coming to our computer science courses, students and parents are sometimes surprised not to see computers in the classroom. They think that since they came to prepare for the exam in computer science, then there should be computers on the tables. But they are not! To what extent is it necessary to have laptops and computers when preparing for the exam in computer science?

This is feature of the exam in informatics. There will be no computer for the exam! And yes, it will be necessary to solve tasks with a pen on a sheet of paper, because it is in this format that the Unified State Examination in Informatics is now taking place. This is a real problem for those who rent it.

Even high school students from specialized lyceums, who are good at programming, may be helpless at the exam in computer science. They, of course, program on computers, that is, in a special environment. But what happens when there is no computer? And not only schoolchildren - even professional programmers can write a program on paper with great difficulty. Therefore, we are preparing for such a complex format right away. We deliberately do not use computers and laptops when preparing for the Unified State Exam in computer science - according to the rule "It is hard in learning, easy in battle."

For several years now, there have been rumors that the Unified State Exam in computer science will be transferred to a computer form. They promised to do it in 2017, but they didn't. Will they do it in 2018? We don't know yet. If such an exam format is introduced, it will be much easier to prepare for the exam in computer science from scratch.

So the year active training to the exam in computer science from scratch, and your result is 26 tasks out of 27 possible. And if you are at least a little familiar with programming, then all 27 out of 27. We wish you to achieve such a result in the exam!

And once again I recommend for the preparation of theoretical material and my book "Informatics. Author's course of preparation for the exam " where the practice of problem solving is given.

Tell your friends!

For effective training in computer science for each task is given a brief theoretical material to complete the task. Matched over 10 training tasks with analysis and answers, developed on the basis of the demo version of previous years.

There are no changes in KIM USE 2019 in informatics and ICT.

The areas in which the knowledge test will be carried out:

Programming;
Algorithmization;
ICT tools;
Information activity;
Information processes.

Necessary actions when preparing:

Repetition theoretical course;
Decision tests in informatics online;
Knowledge of programming languages;
Pull up mathematics and mathematical logic;
Use a wider range of literature - school curriculum not enough to succeed in the exam.

Exam Structure

The duration of the exam is 3 hours 55 minutes (255 minutes), of which one and a half hours are recommended to be devoted to completing the tasks of the first part of the KIMs.

Tasks in tickets are divided into blocks:

Part 1- 23 tasks with a short answer.
Part 2- 4 tasks with a detailed answer.

Of the proposed 23 tasks of the first part examination work 12 refer to the basic level of knowledge testing, 10 - advanced complexity, 1 - high level of complexity. Three tasks of the second part high level complexity, one - increased.

When solving, it is obligatory to record a detailed answer (arbitrary form).
In some tasks, the text of the condition is submitted immediately in five programming languages - for the convenience of students.

Points for tasks in computer science

1 point - for 1-23 tasks
2 points - 25.
3 points - 24, 26.
4 points - 27.
Total: 35 points.

To enter a technical university of an intermediate level, you must score at least 62 points. To enter the metropolitan university, the number of points must correspond to 85-95.

To successfully write an examination paper, you need a clear command of theory and constant practice in solving tasks.

Your formula for success

Work + work on mistakes + carefully read the question from beginning to end to avoid mistakes = maximum score on the exam in computer science.

With modern world technologies and realities of programming, development USE in Informatics has little in common. There are some basic points, but even if you understand tasks a little, this does not mean that you will eventually become a good developer. But there are a lot of areas where IT specialists are needed. You will not lose at all if you want to have a stable income above the average. In IT, you get it. Provided, of course, that you have the appropriate skills. And you can develop and grow here as much as you like, because the market is so huge that you can’t even imagine! And it is not limited only to our state. Work for any company from anywhere in the world! This is all very inspiring, so let the preparation for the exam in computer science be the first small step, after which years of self-development and improvement in this area will follow.

Structure

Part 1 contains 23 short answer tasks. This part contains tasks with a short answer, implying an independent formulation of a sequence of characters. Tasks check the material of all thematic blocks. 12 tasks belong to the basic level, 10 tasks to an increased level of complexity, 1 task to a high level of complexity.

Part 2 contains 4 tasks, the first of which is of an increased level of complexity, the remaining 3 tasks are of a high level of complexity. The tasks of this part involve writing a detailed answer in an arbitrary form.

3 hours 55 minutes (235 minutes) are allotted to complete the examination paper. It is recommended to take 1.5 hours (90 minutes) to complete the tasks of part 1. The rest of the time is recommended to be devoted to the tasks of part 2.

Explanations for grading assignments

The performance of each task of part 1 is estimated at 1 point. The task of part 1 is considered completed if the examiner gave the answer corresponding to the code of the correct answer. Completion of the tasks of part 2 is estimated from 0 to 4 points. The answers to the tasks of part 2 are checked and evaluated by experts. The maximum number of points that can be obtained for completing the tasks of part 2 is 12.
