Enter the score m with a percentage system and convert it into the corresponding grade. The specific conversion rules are as follows: 90~ 100 is a, 80~89 is b; 70~79 is c, 60~69 is d.

Generally speaking, the grades are divided into four grades, from high to low, A, B, C, D. In principle, the proportion of people at all levels in provinces (autonomous regions and municipalities) is: A 15%, B-30%, C-30%, D-* * 25%. Grade D is unqualified, and the specific proportion is determined by the provinces (autonomous regions and municipalities) according to the basic teaching quality requirements and propositions.
