Frequently Asked Questions

Divide your points earned by the total points possible, then multiply by 100. For example, 85 out of 100 points: (85 ÷ 100) × 100 = 85%.

In most grading systems, 85% is a B grade. Typically: 90-100% = A, 80-89% = B, 70-79% = C, 60-69% = D, below 60% = F.

Add up all points earned across tests, divide by total points possible, then multiply by 100. Example: (75 + 80 + 90) out of (100 + 100 + 100) = 245/300 × 100 = 81.67%.
