Ummm… no.

Say you’ve got three criteria, each of them with a range of 0 to 10 (inclusive). If the first one has a weight of 50 and the others each have 25, the rating assigned to the first one gets multiplied by 5 (50 / 10) and the answers to the others get multiplied by 2.5 (25 / 10). The totals are then added up, and end up as a total score out of 100 (50 + 25 + 25).
