可以算班里的 GPA (# of As x 4) + (# of Bs x 3) + (# of Cs x 2) + # of Ds, then divided by # of students. 一般来说 class GPA 在 2.8~3.1 都不算过分。
If the class is exam-based, you can give 15-20% A's, 25-35% B's, 30-40% C's, 5-10% D's, and 5-10% F's. The median can usually be a low B or high C. For project-based class, the grades can be higher.

If your department has certain rules for assessment, such as quota/ percentage of each grade, you just need to follow. Sometimes, such rules are more implicit. Even if there no rules, it's better to be more consistent in assessment avoid unnecessary trouble, unless you have a strong justification for abnormal cases. Consistently having a lot of failures or majority of low grades may not reflect well to the instructor. Students' failure is to some extent the instructor's failure.
