Grade Scale Reference

Standard letter grade scale

A (90–100%) · B (80–89%) · C (70–79%) · D (60–69%) · F (below 60%). Many universities use +/− grades too: A+ (97–100), A (93–96), A− (90–92), B+ (87–89), and so on.

How is weighted average calculated?

Multiply each score by its weight, sum all the results, then divide by the total weight. For example: if a midterm (40% weight) scores 80% and a final (60% weight) scores 90%, the weighted average = (80×40 + 90×60) / 100 = 86%.
