Is it possible to pass his exam on computer science? Personal experience: how to pass the exam on computer science perfectly

A year ago, I was already on the tasks of the exam on computer science. They were complex, sometimes non-ITishnie, provoked mixed reactions and quite interesting discussions.

Computer science is taught in the amount of 1 lesson per week, 7.5 minutes are given for the task. The majority of schoolchildren have very superficial knowledge, and it is generally difficult to speak about algorithmic thinking, the it-outlook and practical experience in using information technologies.

New year, new tasks, new questions for them.

Exercise 1

Artist Robot can move one cell up, down, right and left of the field on which the treasure is located. The robot moves if there are no walls in front of it.

  The robot performs the following algorithm.

What point will be in the path of the robot?

  The task is very interesting, try to solve it, estimating the time and number of attempts. In the answers, point 4 is indicated. Let's see if you can get this answer.

Task 2

In the search engine query language, the “!” Sign in front of a word means that the word should be searched for in the specified form. There are search queries that are simultaneously issued in the same search engine. Arrange them in ascending order of the number of documents found:

A. Airplane, airship or train to! Of Moscow // scored after the space and before the word "Moscow", the editor Habra teaches us punctuation, making it difficult to write tasks as they are
  B. Airplane, airship or train to Moscow
  B. (Airplane | airship | train) & (Moscow)
  G. Airplane & Airship & Train & Moscow

  Tell me, what do you mean by the term "search engine"? After reading the task, I had two versions: Yandex / Google or a database with a SQL engine. Neither option, as far as I can tell, this “query language” is not close.
  In addition, the syntax is generally controversial (comma, brackets, characters of logical operators, Cyrillic without quotes).
  Probably, it means a certain “spherical search system in vacuum”, the working conditions in which it is proposed to be thought out.
  Your version of the answer?

Task 3

The robot is similar to the robot from task 1. Select the point from which the robot began to move, if it stopped at point X, moving along the algorithm.

  The task is interesting because of the slightly confusing wording and uncertainty of the behavior of the robot in case of its stumble on the wall. In the condition and comments - not a word.

Task 4

Arrange the IP address fragments in the correct order.

A. "8.76" B. "9.34" V. ".16" G. "16"

  How many solutions do you see? And how much should a schoolboy see?

Task 5

The pictures show routers, each interface of which has its own IP address. Arrange them to get a route from 10.10.1.2 node

  Do you think this task is close to the realities of the SCS? By the way, from which it follows that the subnet mask exactly 255.255.255.0 is unclear. Without this assumption it is generally unknown how to solve.

Task 6

To encode the background color of a web page, the attribute bgcolor = ”# XXXXXX” is used, where in quotes hexadecimal values ​​of the intensity of the color components in a 24-bit RGB model are specified. What color will be on the page specified by the body tag bgcolor = ”# 808000”?
  A. Brown
  B. Gray
  B. Dark red
  G. Blue

  Schoolchildren are not taught RGB-model and html-tags. If we use the information from the task, then we must also figure out what color will be in the mixture. For example, I am not sure that I know the correct answer. And you? Just do not open the browser or image editor, on the exam there are none.

General impression about the training tasks  (the yellow book of the Eksmo publishing house) by the authors of Samylkina and Ostrovskaya: too many typos, mismatch in the topics of the questions, ambiguous wording. Many questions were baffled and forced not to solve the problem, but to guess what the author meant.

It seems to me that testing students for such tasks still does not provide an adequate assessment of their knowledge of school informatics.

“The performance is incredible!”, Says Lyudmila Vasilyevna about Andrei. Photo: Alexander Katerusha

Each of them answered the questions of the proposed questionnaire from “KP”, where there is an answer to the main question of future generations - what to do to pass the USE for all 100? Today's heroes are Andrei Maximov and his computer science teacher from gymnasium No. 32.

"INFORMATICS AND MATHEMATICS IS CREATIVITY"

Andrei Maximov, 100 points passed computer science:

- When did you start preparing for the exam? What class?

In the tenth grade. I solved the tests, then worked on part C - it is bigger and more difficult. Part C has a compilation. Here is a special preparatory literature studied.

- What, in your opinion, is the most difficult in the exam on computer science?

That part of C, where you have to write the solution yourself. A total of USE gave us 4 hours. Of these, I spent two hours on part C. Indeed, it was not easy.

- What should I do to pass the exam on 100 points?

Prepare: every day, until 12 at night, persevere. Decide, decide, decide. There is no other way out. I set myself the task - to enter the Moscow Institute of Physics and Technology. There in total it is necessary for admission to score 288 points. So I tried to pass everything on 100 points. Did not work out. The Russian language passed by 98 points, mathematics by 94 points, physics by 100, thanks to the Olympiad. In total, it turned out 392 points.

- Could it be written off when passing the exam?

I do not think. And then - what's the point? Well, you wrote off, entered the university. And how will you study? You after the first course deduct. And then, those who write off, do not gain a lot of points. It is better to write independently and honestly and understand which university you can enroll in.

MFTU. There is a specialty Applied Mathematics and Physics with a bias in mathematics. Economic business and computer science. For example, MIPT teachers were engaged in modeling the fall of the Chelyabinsk meteorite. I'm interested. Informatics and mathematics is creativity. Just like physics.

"I WAS DELIGHTED"

Lyudmila Vasilyevna LEXUTOV, computer science teacher:

- Describe the column.

To be honest, when Andrei was in the 10th grade, I didn’t assume that he would be able to pass 100 points. There were some doubts. But he set a goal and achieved. The performance is incredible! There is a goal, there is a desire. All this led to this result. I was delighted. To some extent, these 100 points and my merit, but 70 percent is the work of Andrew.

- Do you have your own observations, which of the students can pass the exam for 100 points?

I was somewhat mistaken in my observations. All the time I thought that a man who quickly thinks and grasps will score 100 points. It turned out that this is not enough. Work is needed here: serious, systematic. If part A and B are not worked through during the preparation process, then part C may not have enough time. On part A and B you need to fill your hand. Andrew realized that. Already at the beginning of grade 11, he solved these test tasks with little or no problems.

The fact that your student passed the exam on 100 points, will affect the ranking of the school? Do you hope to get an award for this high result? How did other graduates of your school pass the exam on computer science?

The rating of the school has grown, because we have two shooters. I myself am already morally satisfied that I have a student who has passed on all 100. If they give me a bonus for this, I will not refuse. The average score that my students received is 83. I think this is not bad.

- What would you change in the USE system?

I like the USE system. They say: write off, there is some corruption ... I think it is to a lesser extent. Children get a real assessment of their knowledge. Something in the exam, I would have improved. It is necessary to give more complex tasks. Although they are every year more and more difficult, they require serious knowledge. But my subject - computer science - is changing. From conventional technology, it grew into a science.

- Have you encountered the facts of cheating on the exam?

I check the exam. In some works it was obvious that the person wrote off. And it is clear that the student wrote, but did not understand what he wrote. This is part C4. You can write off part A. But it will be possible to draw out four, not more.
