About this tool
Test grade conversion turns correct answers (or misses) into a percent and optional US letter. An optional flat curve adds points after the raw percent is known.
Enter correct and total questions — or missed and total, depending on the mode you prefer. Curves here are simplistic; classroom curves can be far more complex.
Weighted categories belong on the grade calculator; finals targeting on the final grade tool.
Formula
percent = 100 × correct / totaloptional: percent + curve
How it is calculated
- Enter correct and total questions (or use missed = total − correct).
- Add curve points if your teacher allows.
- Read % and letter.
Questions
Are the results official advice?
No. Calculate This is an educational tool. Your school's or registrar's official calculation always takes precedence.
