I used to hate mid-term grades, but that was because they used to be such a negative thing. At all institutions I attended before Fayetteville State University, mid-term grades were assigned by instructors only when a student was doing poorly in a course, such as in the D or F range. FSU makes mid-term grading mandatory for all instructors for all students. I find this to be helpful on many aspects, including the as a booster to keep me motivated for finishing off a course strong, or in the case of situations where I may have a B at midterm, it helps to see the letter in the grade system, so I can see exactly how ugly of a grade it is so that I can be motivated enough to improve that grade, no matter what it takes.
Grades are not a matter of fate, they show how hard we push ourselves academically.
