Correct preparation for the exam in computer science from scratch. A collection of ideal essays on social studies Preparing for exam programming

In the exam paper, the exam, several tasks require knowledge of the programming language. In tasks 8, 11, 19, 20, 21, 24, you need to understand and analyze the text of the program, in task 25 you need to write a fragment of the program. In the formulation of the problem, the following languages \u200b\u200bare provided to choose from: BASIC, Pascal, C, Algorithmic language, Python, Natural language.

The only task in which you need to write a complete program yourself is task 27. In the task formulation, you need to write a program “in any programming language”. So which programming language should you choose?

I will express my personal opinion on this, based on the experience of my students passing the exam over the past few years. In the 27th problem of the exam, it is necessary to correctly compose an algorithm, which can be implemented in almost any programming language. Those. in one language the program will be shorter, in another it will be longer, but so far there has never been a problem that could not be solved, for example, in BASIC. In addition, the choice of language does not affect the score. Therefore, if you are fluent in some exotic programming language, you have every right to write a program in it. However, one should take into account the fact that the program will be checked and evaluated.

The FIPI recommendations to the inspectors say: "If the expert is not familiar with this programming language, then he should use the available reference literature or seek help from the consultant or the chairman (deputy chairman) of the subject commission, while observing the inspection regulations." Those. in the case when the inspector has encountered a language unknown to him, he must "observe the inspection regulations", i.e. within the allotted time (and when checking the exam, they are very short), find someone who knows this programming language, and understand the text of your program. Obviously, the probability of underestimation is very high. In addition, it should be understood that schools only use licensed (officially purchased) software. If the school has not purchased the compiler for the language you are using, it will be impossible to test the functionality of your program on your computer.

The practice of the last two years has shown that many assessors do not know the Python language (it appears in the list of allowed languages \u200b\u200bin the USE problems for only the second year). Verification of the text of a program written in C #, Java causes difficulties for the reviewers. Not to mention the rare specific languages. I do not recommend writing a program in a natural or algorithmic language, due to the lack of official rules describing the language. And it is not very pleasant to understand the text written in a language that is not used in practice. I always strongly advise students to describe the algorithm of the program in natural language in order to facilitate the task of the examiner, but the program itself should be written in an understandable, convenient programming language.

For now, I recommend choosing Pascal, C or Basic. These are well-known, common languages. There is a development environment for them in almost any school. This means that the examiner will not have any questions while analyzing your program. The Pascal language has one more advantage: the initially difficult 27th problem was solved in it, which means that you can easily find examples, samples of solutions and analyzes of all types of problems in the literature and on the Internet, which cannot be said about other languages.

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

There are no changes in the KIM USE 2020 in informatics and ICT.

Areas in which knowledge testing will be carried out:

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

Action to be taken when preparing:

• Repetition of the theoretical course;
• Decision tests in informatics online;
• Knowledge of programming languages;
• Improve mathematics and mathematical logic;
• To use a wider range of literature - the school curriculum is not enough for success on the exam.

Exam structure

The duration of the exam is 3 hours 55 minutes (255 minutes), one and a half hours of which it is recommended to devote to the tasks of the first part of the CMMs.

Tasks in tickets are divided into blocks:

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

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

When making a decision, it is obligatory to record a detailed answer (free form).
In some assignments, the text of the condition is submitted in five programming languages \u200b\u200bat once - for the convenience of students.

Points for Computer Science Assignments

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

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

To successfully write the exam paper, you must have a clear command of theory and constant practice in solving tasks.

Your formula for success

Work + work on mistakes + carefully read the question from start to finish to avoid mistakes \u003d maximum score on the exam in computer science.

With the modern world of technologies and realities of programming, development Unified State Exam in Informatics has little to do. There are some basic points, but even if you understand the tasks a little, this does not mean that you will eventually become a good developer. But there are a great many areas where IT specialists are needed. You will not be wrong if you want to have a stable income above average. In IT, you get it. Provided, of course, the availability of appropriate abilities. And you can develop and grow here as much as you like, because the market is so huge that you can't even imagine! Moreover, 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 minor step, followed by years of self-development and improvement in this area.

Structure

Part 1 contains 23 tasks with a short answer. This part contains tasks with a short answer, implying an independent formulation of a sequence of symbols. The assignments check the material of all thematic blocks. 12 tasks refer to the basic level, 10 tasks to the increased difficulty level, 1 task to the high difficulty level.

Part 2 contains 4 tasks, the first of which is of increased difficulty level, the other 3 tasks of high difficulty level. The tasks of this part involve writing a detailed answer in any form.

The examination work takes 3 hours and 55 minutes (235 minutes). It is recommended to devote 1.5 hours (90 minutes) to the tasks of Part 1. The rest of the time is recommended to be devoted to the tasks of Part 2.

Assignment Grading Explanations

Each task of part 1 is estimated at 1 point. The task of part 1 is considered completed if the examinee gave an answer corresponding to the code of the correct answer. Completion of tasks in 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.

Lada Esakova

When a 11th grade student 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.

The high school student's knowledge of mathematics is definitely not zero. Even more so in the Russian language.

The situation with computer science 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 Unified State Exam in Informatics?

The USE control test in computer science contains 27 tasks, which relate to a variety of topics. These are number systems, this is Boolean algebra, algorithms, this is programming, modeling, elements of graph theory.

The Unified State Exam 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 exam in computer science from scratch implies that the student did not go through any of these topics in school. This is usually the case!

For example, a topic such as Boolean algebra, or algebra of logic, is included in the exam in computer science. But it is not studied in schools, even in specialized ones. She is not in the school computer science course, nor in the mathematics course. The schoolboy has no idea about her!

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

Does this mean that problem 23 of the Unified State Exam in computer science is not being solved at all? Of course not! Our students regularly solve it every year. On our exam preparation course in computer science, out of many topics, we take only what is required for the exam. And we pay maximum attention to these tasks.

Why doesn't the school prepare for the Unified State Exam in Informatics?

This is due to the fact that informatics is an optional subject. The Ministry of Education does not give any standards and programs. Therefore, teachers in computer science lessons give students completely different material - who can what. Moreover, some schools do not have computer science lessons at all.

What do high school students usually do in computer science lessons? Do they really play shooters?

Fortunately, at school, in computer science lessons, schoolchildren do not do nonsense, but quite useful things. For example, they are learning Word and Escel. This is useful in life, but, unfortunately, it is absolutely useless for passing the exam.

Moreover, the guys study Word at a serious level, and some even pass exams in computer layout and receive a layout designer certificate. Some schools study 3D modeling. Many schools offer web design. This is a wonderful topic that will be useful in the future, but it has nothing to do with the Unified State Exam! And coming to our courses, the student really prepares for the exam in computer science from scratch.

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

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

There is good news! It takes one year to prepare for the exam in computer science from scratch. It is not easy, but it is possible, and our students prove it every year. The preparation course for the exam in computer science is not very long. You can take the 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 been involved in programming before grade 11, it is hardly possible to master programming in a year. Therefore, problem No. 27 of the Unified State Exam in Informatics will remain unsolved. It is the most difficult one.

It is especially difficult to prepare for the USE in computer science from scratch for those students who have never been familiar with programming and do not know what it is. This area is quite specific, so you need to spend a lot of time preparing for programming and solve a huge number of problems.

In our courses, we will certainly analyze all typical programming tasks. And not once during the exam did the programming problem come as a surprise for our students - they were all analyzed in the courses. And only task 27 is left out for those who have not been involved in programming before the 11th grade.

Coming to our courses in computer science, students and parents are sometimes surprised not to see computers in the classroom. They think that since they have come to prepare for the Unified State Exam in computer science, there should be computers on the tables. But they are not! How necessary is the presence of laptops and computers in preparation for the Unified State Exam in Informatics?

This is a feature of the exam in computer science. There will be no computer on the exam! And yes, it will be necessary to solve the tasks with a pen on a piece of paper, because it is in this format that the Unified State Exam in computer science is now being held. This is a real problem for those who rent it.

Even high school students from specialized lyceums who know how to program well can be helpless on 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 Informatics - according to the rule "It's hard in training, easy in battle."

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

So, a year of active preparation for the exam in computer science from scratch, and your result is 26 problems out of 27 possible. And if you are even a little familiar with programming - then all 27 out of 27. We wish you to achieve such a result on the exam!

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