Kim yege early biology. What can you use on the exam in biology? Can there be changes in the timetable for passing the exam

Almost 1,300 participants took exams in foreign languages ​​(written part), biology and physics as part of the early period of the unified state exam on April 5, 2017, said Andrey Postulgin, deputy director of the Moscow Center for Education Quality, head of the Moscow Regional Information Processing Center.

418 people applied for participation in the Unified State Exam in Biology. The examination work in biology consisted of two parts, including 28 tasks. It took 3.5 hours (210 minutes) to complete it. The established minimum score for this subject is 36 points.

311 people applied for participation in the Unified State Exam in Physics in the early period. The exam paper in physics consisted of two parts, including 31 tasks. It took 3 hours 55 minutes (235 minutes) to complete it. The established minimum score for this subject is also 36 points.

554 people applied for participation in the written part of the exam in foreign languages, 498 of them chose English, 17 - German, 26 - French and 13 - Spanish. The written part in foreign languages ​​consisted of four sections, including 40 tasks. 3 hours (180 minutes) were allocated for the examination work. The established minimum USE score in foreign languages ​​is 22 points. The participants of the early USE-2017 passed the oral exam in foreign languages ​​on April 3.

“The exams were held at 10 examination points located in the educational institutions of the city. Online video surveillance was conducted at all points, and public observers were present in each of them. The exams were carried out using the technology of printing control measuring materials in classrooms and scanning examination materials at the headquarters, ”said Andrey Postulgin.

Participants of the Unified State Exam of the early period will be able to find out their results no later than April 18th. The schedule for the publication of results in all subjects is posted on the official website of the Regional Information Processing Center of the city of Moscow in the section. Exam results and images of the USE and GVE participants' answer forms can be found in the Services and Services section on mos.ru. Educational organizations will receive protocols of exam results on the portal of the Moscow Register of Education Quality. Previous graduates will be able to familiarize themselves with the results protocols at the places of registration for the exam.

The next exam will take place on April 7th. On this day, graduates will take literature and social studies. The schedule of all exams can be found on the website.

Recall that the early period of the unified state exam in 2017 runs from March 23 to April 14, the main one - from May 29 to July 1.

In the early period in 2017, more than 4500 people take part in the unified state exam in Moscow in 2017, of which about two thousand are graduates of the current year, the rest are graduates of previous years. Organized 25 points for examinations, including one exam point - at home, for a participant with disabilities.

As in the previous year, in 2017 there are two "streams" of the unified state examination - an early period (it takes place in the middle of spring) and the main one, which traditionally starts at the end of the school year, in the last days of May. The official draft timetable for the USE "spelled out" all the dates for passing exams in all subjects in both of these periods - including additional reserve days provided for those who, for a good reason (illness, coincidence of exam dates, etc.), could not pass the USE within the specified time frame.

Schedule of the early period for the USE - 2017

In 2017, the early "wave" of the unified state examination starts earlier than usual. If last year the peak of the spring exam period fell on the last week of March, then this season the spring break period will be free from the Unified State Exam.


The main dates of the early period are from March 14 to March 24... Thus, by the beginning of the spring school holidays, many "early students" will have time to pass the tests. And this may be convenient: among the graduates who have the right to take the Unified State Exam in an early wave are the guys who will take part in Russian or international competitions and competitions in May, and during spring break they often leave for sports camps, profile shifts to camps, etc. etc. Shifting exams to an earlier date will allow them to use the latter to its fullest.


Additional (reserve) days the early period of the USE-2017 will be held from 3 to 7 April... At the same time, many will probably have to write exams on reserve dates: if no more than two subjects were submitted on the same day in the last year's schedule on the same day, then in 2017 most elective exams are grouped "in triplets."


Separate days are allocated for only three subjects: the compulsory exam in the Russian language for graduates and all future applicants, as well as mathematics and the oral part of the exam in foreign languages. At the same time, this year, the "early adopters" will hand over the "speaking" before the written part.


It is planned to distribute the March exams by dates as follows:



  • March 14th(Tuesday) - exam in mathematics (both basic and specialized level);


  • March 16(Thursday) - chemistry, history, computer science;


  • 18th of March(Saturday) - USE in foreign languages ​​(oral part of the exam);


  • 20th of March(Monday) - Russian language exam;


  • 22 march(Wednesday) - biology, physics, foreign languages ​​(written exam);


  • March 24(Friday) - Unified State Exam, Literature and Social Studies.

There is a nine-day pause between the main and reserve days of the early period. All additional tests for "reservists" will take place in three days:



  • April 3(Monday) - chemistry, literature, computer science, foreign language (speaking);


  • April 5(Wednesday) - foreign (in writing), geography, physics, biology, social studies;


  • 7 april(Friday) - Russian, basic and.

As a rule, the bulk of those taking the USE ahead of schedule are graduates of previous years, as well as graduates of secondary specialized educational institutions (in colleges and vocational lyceums, the secondary school program is usually "passed" in the first year of study). In addition, school graduates who, during the main period of the USE, will be absent for valid reasons (for example, to participate in Russian or international competitions or to be treated in a sanatorium), or intend to continue their education outside of Russia, may “shoot out” with exams early.


Graduates of 2017 can also, at their own discretion, choose the date for passing exams in those subjects for which the program has been completed in full. This is true primarily for those who are planning - the school course on this subject is read until grade 10, and early passing of one of the exams can reduce tension during the main period of the exam.

Schedule of the main period for passing the exam - 2017

The main period for passing the exam in 2017 starts on May 26, and by June 16, most of the graduates will have completed the exam epic. For those who could not pass the exam on time for a good reason or chose subjects that coincide in terms of delivery, there are reserve examination days from June 19... Like last year, the last day of the exam period will become a "single reserve" - ​​on June 30 it will be possible to pass an exam in any subject.


At the same time, the schedule of exams for the main period of the USE-2017 is much less dense in comparison with pre-term students, and, most likely, most graduates will be able to avoid "overlapping" exams.


Separate examination days are allocated for the delivery of compulsory subjects: the Russian language, mathematics of the basic and specialized level (students have the right to take one of these exams or both at once, therefore, in the schedule of the main period, they are traditionally spread over several days).


As in the past year, a separate day has been set aside for the most demanded elective exam - social studies. And for passing the oral part of the exam in foreign languages, two separate days are allocated at once. In addition, a separate day is allocated for a subject that is not most in demand on the exam - geography. Perhaps this was done in order to spread all subjects of the natural science profile in the schedule, reducing the number of matches.


Thus, in the USE schedule, there are two pairs and one "triple" of subjects, exams for which will be taken at the same time:


  • chemistry, history and informatics;

  • foreign languages ​​and biology,

  • literature and physics.

The exams must be passed on the following dates:



  • 26 of May(Friday) - geography,


  • May 29(Monday) - Russian,


  • May 31(Wednesday) - history, chemistry, computer science and ICT,


  • 2 June(Friday) - profile mathematics,


  • June 5th(Monday) - social studies;


  • June 7(Wednesday) -,


  • the 9th of June(Friday) - written foreign, biology,


  • June 13(Tuesday) - literature, physics,


  • June 15th(Thursday) and June 16(Friday) - foreign oral.

Thus, the majority of schoolchildren will prepare for graduation evenings "with a clear conscience", having already passed all the planned exams and received results in most subjects. Those who were ill during the main examination period, chose subjects that were matched in terms of time, received a "bad" in Russian or mathematics, were removed from the exam, or faced technical or organizational difficulties during the exam (for example, a lack of additional forms or a power outage), will take exams on reserve dates.


Reserve days will be distributed as follows:



  • June 19(Monday) - computer science, history, chemistry and geography,


  • June 20(Tuesday) - physics, literature, biology, social studies, written foreign,


  • 21st of June(Wednesday) - Russian,


  • June, 22(Thursday) - basic math,


  • June 28(Wednesday) - mathematics at a specialized level,


  • June 29(Thursday) - oral foreign,


  • 30 June(Friday) - all items.

Can there be changes in the timetable for passing the exam

The draft official timetable for the exam is usually published at the beginning of the academic year, is discussed, and the final approval of the timetable for the exam takes place in the spring. Therefore, changes are possible in the USE schedule for 2017.


However, for example, in 2016 the project was approved without any changes and the actual dates of the exams completely coincided with those announced in advance - both in the early and in the main wave. So chances are high that the 2017 schedule will also be adopted unchanged.


According to the timetable for the unified state exam in 2017, on April 5, ahead of schedule, exams in biology, physics and the written part of the exam in foreign languages ​​are held.

About 7.5 thousand people applied for participation in the Unified State Exam in Biology. For the USE in this subject, 162 examination points (PES) will be involved.

The exam paper in biology consists of two parts, including 28 tasks. It takes 3.5 hours (210 minutes) to complete it. The established minimum score on the exam in biology is 36 points.

About 7.2 thousand people applied for participation in the Unified State Exam in Physics in the early period, the exam will be held at 152 PPEs.

The exam paper in physics consists of two parts, which include 31 tasks. It takes 3 hours 55 minutes (235 minutes) to complete it. USE participants can use a non-programmable calculator and ruler for the exam. The established minimum score on the exam in physics is 36 points.

About 3 thousand people applied for participation in the written exam in English, the exam will be held at 142 PPEs. 84 participants intend to take the written exam in German in advance, 59 in French, and 25 in Spanish.

The examination paper in foreign languages ​​consists of four sections, which include 40 tasks. The examination work takes 3 hours (180 minutes). The established minimum score on the exam in foreign languages ​​is 22 points. The participants of the early USE-2017 passed the oral exam in foreign languages ​​on April 3.

The course of exams in the regions will be monitored by public observers and employees of Rosobrnadzor. At all examination points, online video surveillance will be conducted, and technologies for printing control measuring materials (CMM) and scanning the answer forms of USE participants directly in the classrooms will be used.
