With the modern world of technology and the 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.

Which programming language to choose, what tasks to focus on and how to allocate time on the exam

Teaches computer science at Foxford.

Different universities require different entrance exams in IT areas. Somewhere you need to take physics, somewhere - computer science. It is up to you to decide which exam to prepare for, but it should be borne in mind that the competition for specialties where physics must be taken is usually lower than in specialties where the Unified State Examination in computer science is required, i.e. the probability of entering "through physics" is greater.

Why then take the exam in computer science?

• It is faster and easier to prepare for it than for physics.
• You will be able to choose from more specialties.
• It will be easier for you to study in the chosen specialty.

What you need to know about the exam in computer science

The exam in computer science consists of two parts. In the first part there are 23 problems with a short answer, in the second - 4 problems with a detailed answer. The first part of the exam has 12 basic level items, 10 advanced level items and 1 high level item. In the second part - 1 task of an increased level and 3 - high.

Solving problems from the first part allows you to score 23 primary points - one point for the completed task. Solving problems in the second part adds 12 primary points (3, 2, 3 and 4 points for each problem, respectively). Thus, the maximum primary points that can be obtained for solving all tasks is 35.

Primary scores are converted into test scores, which are the result of the exam. 35 primary points = 100 test points per exam. At the same time, more test points are awarded for solving problems from the second part of the exam than for answers to the problems of the first part. Each primary score obtained on the second part of the exam will give you 3 or 4 test scores, which in total is about 40 final scores for the exam.

This means that when completing the exam in computer science, it is necessary to pay special attention to solving problems with a detailed answer: No. 24, 25, 26 and 27. Their successful completion will allow you to score more final points. But the price of a mistake during their implementation is higher - the loss of each primary score is fraught with the fact that you will not pass the competition, because 3-4 final scores for the Unified State Examination with high competition in IT specialties can become decisive.

How to prepare for solving problems from the first part

• Pay special attention to tasks No. 9, 10, 11, 12, 15, 18, 20, 23. It is these tasks, according to the analysis of the results of past years, that are especially difficult. Difficulties in solving these problems are experienced not only by those who have a low overall score for the Unified State Examination in computer science, but also by “good students” and “excellent students”.
• Learn by heart the table of powers of the number 2.
• Remember that Kbytes in tasks means kibibytes, not kilobytes. 1 kibibyte = 1024 bytes. This will help avoid calculation errors.
• Carefully study the exam options of previous years. The computer science exam is one of the most stable, which means that you can safely use the USE options for the last 3-4 years for preparation.
• Get to know the different options for wording assignments. Remember that a slight change in the wording will always lead to worse exam results.
• Read the problem statement carefully. Most of the errors in completing assignments are due to a misunderstanding of the condition.
• Learn to independently check completed tasks and find errors in the answers.

What you need to know about problem solving with a detailed answer

24 task - to find the error

25 task requires a simple program

26 task - on game theory

27 task - it is necessary to program a complex program

Problem 27 is the main difficulty in the exam. It is only decided60-70% of USE writers in computer science. Its peculiarity lies in the fact that it is impossible to prepare for it in advance. Each year, a fundamentally new problem is presented for the exam. When solving problem No. 27, not a single semantic error should be made.

How to calculate exam time

Be guided by the data that are given in the specification of control measuring materials for the exam in computer science. It indicates the approximate time allotted for completing the tasks of the first and second parts of the exam.

The exam in computer science lasts 235 minutes

Of these, 90 minutes are allotted for solving problems from the first part. On average, each task from the first part takes from 3 to 5 minutes. It takes 10 minutes to solve problem #23.

There are 145 minutes left to solve the tasks of the second part of the exam, while solving the last task No. 27 will take at least 55 minutes. These calculations were made by the specialists of the Federal Institute for Pedagogical Measurements and are based on the results of exams from previous years, so they should be taken seriously and used as a guide for the exam.

Programming languages ​​- which one to choose

1. BASIC. It is an outdated language, and although it is still taught in schools, there is no point in wasting time learning it.
2. School algorithmic programming language. It is designed specifically for early learning to program, it is convenient for mastering initial algorithms, but it contains almost no depth, there is nowhere to develop in it.
3. Pascal. It is still one of the most common programming languages ​​for teaching in schools and universities, but its capabilities are also very limited. Pascal is quite suitable as the language for writing the exam.
4. C++. Universal language, one of the fastest programming languages. It is difficult to study on it, but in practical application its possibilities are very wide.
5. Python. It is easy to learn at an elementary level, the only thing required is knowledge of English. At the same time, with an in-depth study, Python provides the programmer with no less opportunities than C ++. Having started learning Python at school, you will continue to use it in the future, you will not have to relearn another language in order to reach new horizons in programming. To pass the exam, it is enough to know "Python" at a basic level.

Good to know

• Works in computer science are evaluated by two experts. If the expert evaluation results differ by 1 point, the higher of the two points is assigned. If the discrepancy is 2 points or more, the work is rechecked by a third expert.
• A useful site for preparing for the exam in computer science -

Consist of two parts. The first part includes tasks in which you need to give a short answer. To tasks from the third part it is required to give a detailed answer.

Changes in the demonstration versions of the Unified State Examination in Informatics

Demonstration versions of the Unified State Examination in Informatics for Grade 11 for 2004 - 2014 consisted of three parts. The first part included tasks in which you need to choose one of the proposed answers. The tasks from the second part were required to give a short answer. To the tasks from the third part it was necessary to give a detailed answer.

In 2013 and 2014 in demo versions of the exam in computer science the following changes:

• was in the second part of the work.

In 2015 in demo in informatics was variant structure changed and optimized generally :

Option became be in two parts(part 1 - short answer questions, part 2 - ).

Numbering assignments has become through throughout the variant without letter designations A, B, C.

Was the form of recording the answer in tasks with a choice of answers has been changed: the answer has become necessary to write down the number with the number of the correct answer (and not mark with a cross).

It was reduced the total number of tasks (from 32 to 27); It was reduced from 40 to 35 maximum amount primary points.

The reduction in the number of tasks was made due to enlargement of the subjects of assignments, information related to the subject and complexity of tasks in one position. Such enlarged positions became: No. 3 (storage of information in a computer), No. 6 (formal execution of algorithms), No. 7 (technology for computing and visualizing data using spreadsheets) and No. 9 (transfer rate of sound and graphic files). AT demo 2015 presented several examples of each of tasks 3, 6, 7 and 9. In real options for each of these positions only one exercise.

• Was quest sequence changed.
• The part of the work that contained open-ended questions, hasn't changed.

AT demo version of the Unified State Examination in Informatics 2016 compared with Demo 2015 Informaticsno significant changes: only the sequence of tasks 1-5 has been changed.

AT demo version of the Unified State Examination in Informatics 2017 compared with Demo 2016 Informaticsthere were no changes.

AT demo version of the USE 2018 in informatics compared with Demo 2017 Informatics the following changes:

In task 25 removed possibility writing an algorithm in natural language,

• Examples texts of programs and their fragments in the conditions of tasks 8, 11, 19, 20, 21, 24, 25 in C language are replaced by C++ examples.
