Carried out this exam in the main subjects - Russian language, literature and mathematics. To retake the examas any other exam. Only a few conditions. To retake the final test only if the scores obtained during testing were below established by Rosobrnadzor minimum. At least this is defined only after the exams are over. Because it is calculated on the basis of the analysis of all works. And then have to see how many of the items "failed" graduate.
If the bad were put only one item of the two main, to retake the exam in this academic year in a specially designated additional days.
If the graduate does not cope with the final tests in two subjects, then to retake them, he can only next year. But on the passport it would have no impact. If the doctrine gets a bad mark on the main subject, your grade in this class is based on the arithmetic mean among the results of the exam and the earlier school certification. This so-called rule of "+1".
If the graduate could not overcome the minimum threshold on points, handing the unified state exam on subject from the list of "optional", then retake this final certification will only be possible for the next academic year.
