Academic grading in Belarus follows a ten-point grading scale. This scale has been used since 2002. It is used in primary, secondary and higher education.
Marks "1" and "2" are considered as "fail" at school. In higher education "3" is also considered as "fail". Mark "0" is comparing to "F-" in the USA for refusing to do some work or an exam.
Besides grades, a "pass" / "no pass" mark may be used for some subjects. E.g. it's an "art" subject in secondary school.
