Every year in Russia there is a state certification of schoolchildren who complete their graduation classes. The law provides for early and main delivery periods.

In 2016 USE year early period started at the end of March and continues to this day. In early April, there will be such exams, as well as . Since these subjects are not compulsory, students have the right to choose them on their own.

Physical discipline for last years gained considerable popularity and many schoolchildren, who aspire to get into physics and mathematics universities in the future, apply for the delivery of this subject.

Students have several options for obtaining final information on the exam, but you should be aware that results early USE in Physics 2016 will only be available at the end of the trial period.

There are several ways, but everything can be divided into two groups:

• when the student personally applies to the organizers of the state certification;
• the ability to obtain a result according to passport data by accessing electronic resources on the Internet.

Each option is free and quite affordable for any student.

When will the results of the early exam in physics be known?

As in chemistry, the examination in physical discipline passed April 2. Previously, data on the results of the test will be published on the portal of the Ministry of Education April 13.

According to the decree of the department, examiners and organizers of state certification are given no more than 10 days. In some situations, the deadline may be extended. up to 12 days, on the basis of a separate order.

Some sites speculate on the need for schoolchildren to find out the results of the exam, and offer them to get the results for a fee the next day, however, such actions are obviously fraudulent and you should not contact such electronic resources.

All information is provided to children completely free of charge and strictly at the end of the period allotted for verification.

Where can you get results?

About how and where can find out the results of the early exam in physics there is a lot of information. Such information can be obtained in detail on the RCOI website. Lists of educational sites are published there, where the results are posted immediately after verification and are accurate. In turn, on FIPI official website you can find the phone number hotline» specific region and get the exact answer to this question there.

In general, there are several ways to find out the results:

1. The teenager must contact the leadership of the school that conducted the test, submit an application and receive an official certificate on the passport. This document indicates the upper and lower score levels and the score determined in accordance with the special rating. In the future, the school management places the information received on a special stand. The disadvantage of this method is that the student cannot familiarize himself with the work itself, if necessary, protest decision and analyze the mistakes made.
2. The next way to get information about passing the state exam is to contact the official electronic resource Ministry of Education. There you can find out about the number of points scored, evaluation and see a scanned copy of the work itself.
