Ukrainian universities use a traditional 5-point scale:
"5" = "excellent"
"4" = "good"
"3" = "satisfactory"
"2" = "unsatisfactory".
"5", "4", "3" can be described as "Passed", "2" - as "Fail". Students who get a failing grade of "2", have two more chances to pass an examination. Since 2006 (and even earlier in some universities), university students are graded on a rating scale of 0 to 100. These grades can be transformed to the 5-point scale approximately as follows (this system may vary a little from university to university and may change from time to time):
from 90 to 100 means "5" --- A
from 75 to 89 means "4" ---- B,C
from 60 to 74 means "3" ---- D
from 0 to 59 means "2" ---- E
Both the rating scale and the 5-point scale are used in university registers. Some lecturers prefer to use A-F-point scale to rate students during their passing the exams.
As for secondary schools, they also used the above-mentioned 5-point scale till 2000. Since 2000 secondary schools use a 12-point scale, which could be transformed into the traditional 5-point scale as follows:
"12" = "5+"
"11" = "5"
"10" = "5-"
"9" = "4+"
"8" = "4"
"7" = "4-"
"6" = "3+"
"5" = "3"
"4" = "3-"
"3" = "2+"
"2" = "2"
"1" = "2-"
Here signs "+" and "-" denote respectively better and worse version of a mark, for example, "4-" means "somewhat worse than good".
