Frequently Asked Questions — Grade Calculator
How do I calculate my test grade percentage?
Divide the points you earned by the total possible points, then multiply by 100. For example, 78 out of 90 points = (78 ÷ 90) × 100 = 86.67%. Enter these numbers in the Test Grade tab to get the percentage and letter grade instantly.
What GPA does each letter grade correspond to?
Standard letter grade thresholds: A+ (97–100), A (93–96), A- (90–92), B+ (87–89), B (83–86), B- (80–82), C+ (77–79), C (73–76), C- (70–72), D+ (67–69), D (63–66), D- (60–62), F (below 60).
How do I calculate a weighted course grade?
Multiply each assignment score by its weight percentage, add them up, and divide by the total weight. For example, if homework is 30% and you scored 85, and the exam is 70% and you scored 90: (85 × 30 + 90 × 70) / 100 = 88.5%.
