How it works
The formula behind this calculator.
Final grade → letter via institution's cutoff
- score
- Numeric grade 0–100
- cutoffs
- Letter-grade thresholds
Final scores are mapped to letters via the school's cutoffs. Some schools also use plus/minus (A−, B+, etc.) and weight AP/honors courses.
Example: 88% → B (assuming A≥90, B≥80, C≥70, D≥60, F<60)

Tips
- 💡 Different schools use different scales (A=4.0, A=5.0 weighted, etc.). Check your institution's policy.
- 💡 Some courses count for more (e.g. AP, honors). Add the bonus when entering your grades.
