Course Retake Grade Policy Calculator

See the GPA effect of retaking a course under four common policies

Enter your original grade, expected retake grade, and credit hours, then pick your institution's retake policy — grade replacement, grade average, highest grade, or both grades counted — to compute the exact effect on your overall GPA.

What is grade replacement?

Under grade replacement, also called grade forgiveness, only the retake grade counts toward your GPA and the original grade is excluded from the calculation while still appearing on the transcript. This usually gives the biggest GPA boost.

Retaking a course can help or barely move the needle depending entirely on how your school counts the second attempt. This calculator models the four common policies so you can see the real GPA effect before you decide to repeat.

How it works

Your GPA is total grade points divided by total credits. The tool starts from your current totals, removes the original course’s contribution, then adds it back according to the chosen policy:

4.0 scale: A 4.0, A- 3.7, B+ 3.3, B 3.0, B- 2.7, C+ 2.3,
           C 2.0, C- 1.7, D+ 1.3, D 1.0, F 0.0

replace : course counts retake grade only
average : course counts (original + retake) / 2
highest : course counts max(original, retake)
both    : course appears twice; both grades counted over doubled credits

The new overall GPA is then the rebuilt grade-point total over the adjusted credit total.

Example

A 3.20 GPA over 60 credits, retaking a 3-credit C (2.0) for an expected A (4.0): under replacement the course jumps to 4.0 and the GPA rises noticeably; under average it only counts as 3.0; under both-counted the extra 3 credits dilute the gain.

Notes

Letter-to-point mappings vary slightly by school, and some cap how many courses qualify for forgiveness. Confirm your registrar’s exact scale and limits.
