How the grade is calculated
Each grade is multiplied by its weight. The results are added together and divided by the total weight. For example, a 90 worth 20 and an 80 worth 30 give (90 × 20 + 80 × 30) ÷ 50 = 84.
To find the grade needed on the remaining work, the calculator solves for the average that brings the overall grade up to your goal: (goal × total weight − points earned so far) ÷ weight remaining.
Weights can be percentages that add up to 100, or points. Either way, enter the weight of the remaining work on the same scale.
