how do i calculate my final grade in a class?
Current grade is 70% (or C-). Final exam weight is 50%. Required grade is 80% (or B-). The final exam grade is equal to 100% times the required grade, minus 100% minus the final exam weight (w) times the current grade (g), divided by the final exam weight (w): Final exam grade =. = ( 100%Ãrequired grade - (100% - w)Ãcurrent grade ) / w. = ( 100%Ã80% - (100% - 50%)Ã70% ) / 50% = 90%. So the final exam grade should be 90% (or A-).
