If you have a 101 in a class in school, and you have done over 15 assignments in that class, 3-4 of them being tests. If fail the next test or make a zero, how far would my grade drop from a 101?

Question

Basically saying that my overall grade in this class currently is a 101, and I have already taken 3-4 tests, and I go to take another test, but I make a zero on it, how far would my grade drop from a 101, if this happens?

Answer 1

if next grade = 0, then the grade average would drop to 3(101)/4 = 303/4 = 75.75 = 76

if you've already taken 3 of 4 tests and each has the same weight
