Column (a) is the midterm exam score, columns (b)-(i) are homework scores, with column (j) being the sum of all homework scores; then column (k) multiplies (j) by 0.673401 so that the highest total will be 100, which makes the weighted total have proper percentages (20% for midterm, 30% for final, 50% for homework). Column (l) is the score on the final exam, but this is multiplied by 1.07527 in column (m) so that the highest final exam score equates to 100 (that way, percentages will be properly weighted).

Column (n) is the weighted total from columns (a), (k) and (m).

The distribution of scores in column (n) is presented in the graph gradist.gif; the horizontal line show the mean at about 75 (standard deviation is about 14). Tentatively, scores above 79 will be in "A" territory, with the others in "B" range, though one low score looks like "C".
