About the Grade Calculator
Most courses don't average your scores evenly — a final exam usually counts more than a single homework set. This tool uses the weighted-average method: each score is multiplied by its weight, the results are summed, and the total is divided by the combined weight.
That single number is then matched against a standard grading scale to show you a letter grade, so you instantly know where you stand before report cards or transcripts are finalized.
