How to use
- 1Enter your current GPA and total credits, plus the credits of the repeated course.
- 2Choose your school's policy: replacement (both the old and new grade counted) or averaging (only the new grade counts).
- 3Enter the original and new grade to see how your GPA changes under each policy.
Formulas
Replacement: new GPA = (current QP − old QP + new QP) ÷ credits • Averaging: GPA = (current QP + new QP) ÷ (credits + course credits)Policies differ by institution. Replacement removes the original quality points and adds the new one using the same credits. Averaging keeps the original and adds the new attempt, increasing total credits.
Examples
GPA 3.0 over 60 credits; repeat a 3cr C with an A
Replacement: remove 6.0 QP, add 12.0 → (180 − 6 + 12) ÷ 60 → 3.10. Averaging: 63 credits → 192 ÷ 63 → 3.05.
Replacement 3.10 • Averaging 3.05
About
The Course Repeat GPA Calculator shows how retaking a course affects your grade point average under two common institutional policies. Some schools replace the original grade, while others average both attempts into your record. Enter your current GPA, total credits, the repeated course's credits, and the original and new grades to compare both outcomes side by side. Students facing a required retake use this tool to decide whether repeating a course is worthwhile and to understand exactly how much their GPA can improve. Always confirm your school's policy before planning around it.
Frequently asked questions
Which repeat policy is more common?
Many US universities use grade replacement, but some average both attempts. Check your institution's catalog — the difference can be significant.
Does the repeated grade replace the credit total too?
Under replacement, credits stay the same. Under averaging, the course credits are counted twice.
