i have a question regarding how

grade is curved in college. I had thought the scores within mean +/- 1SD  is B. Above 1 SD is A, below 1 SD, but within -2SD is C. So on average, 15% A, 60% B, and 15% C.

Am I right? My son's high school does not curve, or the teacher curves based on their own method. So i do not know how the grade should be curved.

• 应该都是教授根据每次考试的难易程度定的吧 -中坛太抖- ♂ (0 bytes) () 12/24/2017 postreply 22:13:13

• 当然不是这样硬性规定的。可操作的范围很大：前提是如果curve是合理且没有学生反对的话。其实还有很多别的办法。 -linda2- ♀ (0 bytes) () 12/24/2017 postreply 22:29:07
