Normal university exam results are mid-term+final+normal performance (normal performance), so the score will generally exceed 60 unless you fail.

Make-up exam because it is the final comprehensive score of 60. So this is an opportunity to make up for it. Of course, it can't be counted like the final. You reviewed for several months more than the students who failed in other courses. It's unfair if you take 100, which is more than other students.

Therefore, even if you add 100, your score can only be 60.
