Frequently Asked Questions

Does this account for course credits?

No. It is a simple average of four course percentages. A 2-credit course and a 4-credit course have the same influence here, so use a weighted calculation when credits differ.

How do I turn this average into a GPA?

Use the percentage-to-GPA converter, or apply your school’s letter-grade table. GPA conversion is not a single universal formula.
