OGE computer science real options with solutions. Preparation for the OGE in computer science

Educational portal“I WILL SOLVE OGE” is my personal charity project. It is developed by me, as well as by my friends and colleagues, who care about the education of children more than about themselves. Not funded by anyone.

The distance learning system for preparing for the exam “SOLVE OGE” (http://reshuoge.rf, http://oge.sdamgia.ru) was created by the creative association “Center for Intellectual Initiatives”. Head - mathematics teacher at gymnasium No. 261 of St. Petersburg, Honorary Worker of General Education of the Russian Federation, Teacher of the Year in Russia - 2007, member of the Federal Commission for the Development of Testing and Measuring Materials in Mathematics for the Unified State Examination in Mathematics (2009-2010), expert of the Federal Subject Matter Unified State Exam commission in mathematics (2011-2012), deputy chairman of the regional subject commission of the Unified State Exam in mathematics (2012-2014), leading expert of the Unified State Exam in mathematics (2014-2015), federal expert (2015-2016) Gushchin D.

SERVICES OF THE EDUCATIONAL PORTAL “I WILL SOLVE OGE”

To organize thematic repetition, a classifier of examination tasks has been developed, which allows you to sequentially repeat certain small topics and immediately test your knowledge on them.
To organize ongoing knowledge monitoring, it is possible to include in training options works of an arbitrary number of tasks of each examination type.
To conduct final tests Testing is provided in this year's Unified State Exam format using one of the options preset in the system or an individual randomly generated option.
To control the level of preparation, the system keeps statistics of topics studied and tasks solved.
To familiarize yourself with the rules for checking examination papers, it is possible to find out the criteria for checking part C tasks and check open-ended tasks in accordance with them.
For a preliminary assessment of the level of preparation, after passing the test, a forecast of the test examination score is reported on a 100-point scale.

The task databases were specially developed for the “SOLVE OGE” portal, and were also compiled on the basis of the following sources: tasks from open banks and official collections for preparing for the OGE; demo versions of OGE and exam assignments, developed by the Federal Institute of Pedagogical Measurements; diagnostic works prepared by the Moscow Institute open education; training work carried out by educational authorities in various regions of the Russian Federation.

All tasks used in the system are provided with answers and detailed solutions.

State process final certification involves the use of standardized tests to control the quality of students’ training and, in general, everything educational process in high school.

To successfully pass the OGE in computer science 2018, preparation must begin at the beginning of the academic year, taking into account the innovations being adopted.

Structure of the 2018 OGE in computer science

The proposed set of tests is divided into 2 group categories:

Part 1 of the examination paper contains 18 tasks - 11 basic level difficulty and 7 increased difficulty levels. The first six tasks with one correct answer out of four options (these are tasks of category A) and twelve tasks where the answer can be either a word, a number or an entire digital sequence (these are tasks of category B).
Part 2 contains 2 tasks high level difficulty - the graduate is offered two tests. But everyone needs the most detailed and detailed answer. Most likely, you will need enough difficult decision. In task numbers 19 and 20, you will need to write a program for two proposed tasks (these are tasks of category C).

After completing the tasks of Part 1, the examinee submits a form for recording answers and proceeds to completing the tasks of Part 2.

The duration of the exam is 150 minutes. Test developers recommend completing tasks in categories A and B in 75 minutes, freeing up the remaining time for writing a programming task (category C).

Practical part

Previously, the student selects software and hardware and the appropriate language to complete the second part of the OGE.In accordance with specified parameters he is given workplace, equipped with a computer.To complete task 19, you need a program to work with spreadsheets. To complete task 20.1, it is recommended to use learning environment performer “Robot”, the second version of the task (20.2) involves writing the algorithm in the programming language being studied.

Options for acceptable languages for writing a program:

Algorithmic language
BASIC
Pascal
C++
Python

An excellent opportunity to practice the examination process, study possible types of tasks, and even repeat the curriculum - demo version of the OGE in computer science 2018 .

Additional information about the OGE 2018

When performing the first and second categories of tasks, the use of technical devices is not allowed: calculators, computer equipment, mobile phones. Reference books and books on computer science are also prohibited.

Psychological secrets of successful exam preparation

Taking the exam

“Luck always smiles on those who have worked hard,” says an English proverb. I would like to add: “and to those who know how to show the results of their work.” In an exam, that's exactly what you do - demonstrate what you've learned. So do it calmly and confidently. Try to change your idea of the exam - it’s not torture, not execution, but simply a test of your knowledge, especially since you know everything (or almost everything).

On the day of the exam

1. Pre-exam stress is often accompanied by a lack of appetite. But even if “a piece doesn’t fit into your throat,” you definitely need to eat at least a little. Otherwise, in a state of stress, a sharp decrease in blood sugar levels may occur and accompanying symptoms may occur - trembling, sweating, weakness, dizziness, headache, nausea... It won’t take long for you to faint.

2. You should not go to the exam with a full stomach. Breakfast should be light, containing foods rich in protein and carbohydrates. In the morning before the exam, it is best to eat yogurt, as well as cottage cheese, scrambled eggs, milk porridge or muesli, a sandwich with cheese or honey and drink tea with lemon and sugar. You shouldn’t “pick yourself up” with strong coffee. If your nerves are on edge, but you realize that your body needs food, eat 1 tsp. honey, 2 walnuts, 3 pieces of dried apricots and drink a glass of biokefir. 1-2 bananas, a handful of raisins and a fruit milkshake will also help maintain your strength.

3. Exclusively effective means music helps relieve pre-exam stress . When getting ready for the exam, turn on recordings of a bravura march, czardas or energetic guitar flamenco, and you will be convinced that your fear and inner trembling will disappear. If you love classical music, you will be helped by Bach's preludes and fugues for organ, Tchaikovsky's Fifth Symphony, and all the orchestral works of Alexander Scriabin. Bach's music, by the way, is very effective if intense intellectual work is to be done. Compositions by Bryan Adams, Tina Turner, Bon Jovi and Riccardo Foglia also set the mood for battle.

4. But what you should never do is take sedatives. The result could be disastrous. Lethargy and lethargy will not allow you to concentrate!
Before leaving the house, apply a few drops of lavender, basil or mint essential oil, which has calming properties, to your temples or wrists. You can also drop this oil on a handkerchief and then periodically inhale its aroma during the exam.

Techniques for dealing with fear

1 . Stop being afraid! Many people are well aware of the state of panic before exams: “I don’t know anything! I don’t remember anything!” Try to direct your thoughts in a different direction: “I worked long and purposefully, I did everything in my power, I still know something from all the material and quite well.”

2. Do breathing exercises. This is the fastest, easiest and most effective way overcoming feelings of stress and panic. Close your eyes and breathe slowly and deeply. Exhalation should be 2-3 times longer than inhalation. As you inhale, imagine that you are sniffing your favorite scent through your nose. Exhale through slightly closed lips as if you want to blow out a candle flame or blow on a spoon of hot soup. 3-5 minutes after the start of breathing exercises, you can add self-hypnosis formulas to them:« I relax and calm down", synchronizing them with the rhythm of your breathing. At the same time, the words “ I" And " And"should be pronounced in inhale, and the words “ relaxing" And " I'm calming down" - on exhale.
You can also say to yourself:

“I am calm and confident”

“My memory works well. I remember everything"

“I can prove that I worked hard and learned everything.”

Autotraining - efficient technique: The brain perfectly obeys such commands.

3. Learn to never think about failing an exam.. On the contrary, you need to mentally paint yourself a picture of a confident, clear answer, complete victory. We get what we think hard about, literally programming ourselves for the end result. And for this result to satisfy us, we need to think about the good, setting ourselves up for success: “I will succeed, at the right moment I will remember everything.”

4. Don't get caught up in other people's anxiety. As a rule, in front of the door of the auditorium in which the exam is taking place, there is a crowd of students shaking with fear, discussing how strict and picky this or that examiner is and from time to time saying: “Oh, I’m definitely going to fail today! Everything flew out of my head! I’m already shaking all over!” Do not crowd together with them, so as not to be “infected” by their fear. Experience your anxiety alone, step aside, wander along the corridor, look out the window.

5. Relieve tension. The simplest movements will help you get rid of painful discomfort. Make a few circular movements with your head, stretch your arms, and shrug your shoulders. If possible, box, throwing punches into an empty space and imagining that you are punching your fear.

IN stressful situation It's good to yawn. By yawning sweetly three to five times, you will not only reduce anxiety, but also activate your brain. To trigger the yawn reflex, you need to use your middle fingers to massage the muscles between your ear and cheek.

6. Do self-massage. A light massage of the back of the head distracts from obsessive fear and also helps to significantly increase intelligence. Massaging the tips of the little fingers, as well as performing yoga for the fingers, the so-called mudras, helps relieve emotional stress. This word refers to the joining of fingers in a certain combination.
Thus, the mudra of the Earth helps with stress, deterioration of psychophysical condition, increases self-esteem and self-confidence. To perform it, press the ring and thumb fingers of both hands tightly against each other with the pads, straighten the remaining fingers and spread them slightly apart. It is useful to do this gesture as often as possible and keep your fingers in this position for as long as possible.
If you are under severe stress, put left hand on the table, palm down. With your right hand, for 3-5 minutes, in a clockwise circular motion, massage the point of intersection of the conventional lines of the thumb and index finger, while keeping the thumb as far as possible from the index finger. Then change your hand, but now make movements counterclockwise.

OGE in computer science is one of the exams that is taken at the student’s choice. To enter the 10th grade after the 9th grade, you need to choose 2 subjects of your choice and 2 disciplines are mandatory. Computer science is chosen by those who enter a class with a certain specialization or plan to enter a college or technical school where this subject is needed. Also, many choose computer science because it seems to be the most simple option. If you know a computer and have not chosen a subject to take, computer science is worth paying attention to.

The exam is divided into two parts - written and practical, which is performed on a computer.

The first part includes 18 tasks (the number may change every year), the difficulty level is basic. The goal is to test students’ theoretical knowledge for compliance with the norms and standards of the program. Main topics and focus of assignments: converting numbers from one number system to another, converting units of measurement, theoretical knowledge on all topics of the course. If you learn to do similar tasks, remember the features and solution algorithm, there will be no problems in the exam. Also in this part there are programming tasks - this does not require specific knowledge and special abilities, it is enough to learn the algorithm.
The second part requires you to complete two tasks on the computer. Moreover, you need to cope without the help of the Internet. The tasks are aimed at testing work, e.g. Office package or programming environment. The first task, most often, is on Excel skills: find the sum, use formulas and graphs to demonstrate any values. Programming is performed in the Kumir, Python, Pascal environment. The student receives a task and completes it - the result should be a worker, not complex algorithm.

It is quite possible to complete the course and prepare for the exam with basic skills. The main thing is to practice writing algorithms, study theory, and learn how to perform tests. It will help with the latter online resource“I will solve the OGE in computer science” - a lot of tasks are collected here different levels difficulties, after passing which the student will be able to easily pass the exam with a high score.
It is recommended that you begin your preparation by familiarizing yourself with , which outlines all the topics worth paying attention to. This will help create a schedule and preparation plan. Clearly set goals and an action plan, a little self-discipline and you can master the material even in six months. To master programming, you can use the help of a teacher, study textbooks on your own, study with a tutor - it’s a matter of choice.
Programming is considered the most difficult topic - spend more time on it. But classes with the help special resource the site will allow in online mode Gain experience in solving tasks of varying complexity. Only by knowing how to use the information you have learned can you pass the OGE in computer science with a high score.

IN this section We present to your attention information on the 9th grade exam "Informatics" in the OGE format. Available demo options, reference books with theory, exam specifications and practice tests. You can find information about the exam format below.

Exam Information

The computer science exam consists of two parts and 20 tasks.

First part contains 18 tasks of basic and advanced difficulty levels

6 tasks with selection and recording of the answer in the form of one digit
12 tasks, implying that the examinee independently formulates and writes down the answer in the form of a sequence of characters

Second part contains 2 tasks of high difficulty level.

The tasks of the second part imply practical work students at the computer using a special software. The result of each task is separate file. Task 20 is given in two versions: 20.1 and 20.2; The examinee must choose one of the options for the task.

Among tasks 1–6, tasks from all thematic blocks are presented, except for tasks on the topic “Organization of the information environment, information search”; among tasks 7–18 there are tasks on all topics except the topic “Design and Modeling”.

The tasks in Part 2 are aimed at testing practical skills in working with information in text and tabular forms, as well as the ability to implement a complex algorithm. In this case, task 20 is given in two versions: task 20.1 involves developing an algorithm for a formal executor, task 20.2 is to develop and write an algorithm in a programming language. The examinee independently chooses one of two options for the task, depending on whether he has studied any programming language.
