that looks sensible to me.
My wife is trying to figure out her final grade and her tests and quizes were weighted differently. There were 3 tests worth 50 points each with a weight of 90%. She got 132 out of 150 points on the tests. I am not sure of the number of quizes but she said she got 50 out of 50 points and it is weighted at 10%. How do you determine the final grade. Here is my attempt.
