Grade Calculator

Each category score is multiplied by its weight, then summed: 92 on homework worth 20% contributes 18.4 points; 78 on exams worth 50% contributes 39. Your grade is the total. The practical insight students miss: a point of improvement in a 50% category is worth 2.5× a point in a 20% category — effort allocation should follow the weights.

Leave the score blank — the category is excluded and the remaining weights are rescaled proportionally, which is exactly how most instructors and LMS gradebooks (Canvas, PowerSchool) report a mid-semester grade. Your displayed grade can therefore drop when a heavy category starts filling in, even with decent scores; that's the rescaling unwinding, not a math error.

The most common US scale: A− starts at 90, B− at 80, C− at 70, D− at 60, with plus grades at the 7s (87 = B+) and flat grades at the 3s. Plenty of syllabi shift these — some give A− at 89.5, some don't award A+ — so the percentage here is exact and the letter is the standard mapping; your syllabus wins any conflict.

If assignments are equally weighted within the category, average the percentages. If they're point-based, total your earned points divided by total possible — that's usually what the LMS shows per category already, and it's the number to enter here. Dropped-lowest policies apply before averaging.
