Missing information - you need the worth (weight) for every grade, not just for some of them. The way you calculate this so-called "weighted average" is to multiply each grade by its weight, and add everything up. Then you divide by the total "weight". Example: exam 1: grade is 80; weight is 40. exam 2: grade is 70; weight is 60. 80 x 40 + 70 x 60 = 3200 + 4200 = 7400. Divide this by the total weight (40 + 60 = 100), and you get a weighted average of 74.
