GPA Calculator (4.0 / 4.3 / 4.5 scales)
GPA is a credit-weighted average: Σ(grade × credits) / Σ(credits). Different schools use different scales — US standard is 4.0 with A=4.0; A- = 3.7, etc. Some US schools award A+ = 4.3 (Cornell, Stanford). Korean universities typically use 4.5 (A+ = 4.5, A = 4.0, B+ = 3.5, …). This tool handles all three, supports an unlimited number of courses with editable name/grade/credits, and shows GPA, total credits, and total quality points.

Frequently asked questions
- What's the difference between 4.0 and 4.3?
- On the 4.0 scale, A and A+ are both worth 4.0 — the '+' doesn't add weight. On 4.3, A+ is worth 4.3, so a transcript full of A+ beats one full of plain A's.
- Why is Korea on 4.5?
- Korean universities historically used absolute grading with A+ at 4.5 to give more granularity at the top end. Lately many schools also publish 4.3 conversions for international applications.
- How do I handle Pass/Fail courses?
- Don't include them — they have no grade points. Just leave them out of the list. They affect your credit total but not your GPA.
- What about transfer credits or repeated courses?
- Policy varies by school. Common rules: transfer credits count toward graduation but not GPA; repeated courses replace the old grade (some schools) or average it in (others). Check your school's catalog.
