Figuring out grades is not just as simple as calculating the average of test or homework scores. The first place to start would be the mathematical formula of the professor or teacher. Ask what percentage of each assignment represents your final grade. Letter grades loosely configured are as follows: 100-95 is A, 90-94 is AB, 89-85 is B, 80-84 is BC, 79-75 is C, 70-74 is CD, 65-69 is D, 64
. and under F or E. However, keep in mind that the ultimate decision comes from the teacher's scale.
