Frequently Asked Questions
Divide the points you earned by the total points possible, then multiply by 100. For example, if you scored 42 out of 50: (42 / 50) × 100 = 84%.
Standard grading scale: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%). Some schools use different scales or plus/minus grades.
To get 90% (A grade), you can miss 10% of questions. On a 50-question test: 50 × 0.10 = 5 questions. You can miss up to 5 questions and still get an A.
