FAQ

How is percentage calculated?

Percentage = (Correct ÷ Total) × 100. Getting 45 out of 50 = 90%.

What percentage is an A?

Typically 90%+ for an A, but grading scales vary (some use 93%+ for A, 90-92% for A-).

How many wrong for a certain grade?

Calculate: (1 - grade threshold) × total questions. For 90% on 50 questions: (0.10) × 50 = 5 wrong maximum.

What about partial credit?

Add up total points earned divided by total points possible instead of correct/total questions.
