GPA Retake Calculator
See how retaking a class changes your GPA under grade replacement (forgiveness) or grade averaging — new cumulative GPA, quality points and the gain from the retake.
How it works
Quality points = GPA × credits · Replacement: new GPA = (QP − old points × course credits + new points × course credits) ÷ credits · Averaging: new GPA = (QP + new points × course credits) ÷ (credits + course credits)
Under grade replacement (also called grade forgiveness), the retake grade takes the place of the original in your GPA, although both usually stay on the transcript. Under averaging, both attempts count, so the retake adds credits and quality points without removing the old grade. Grade points use the common 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0). Policies differ by school, and graduate or professional schools often recalculate GPA with every attempt.
Worked example
A 2.80 GPA over 60 credits holds 168 quality points. Retaking a 3-credit F and earning a B under grade replacement: 168 − 0 + 3 × 3 = 177 quality points ÷ 60 = 2.95, a change of +0.15. Under averaging it would be 177 ÷ 63 = 2.81.

Frequently asked questions
Does retaking a class replace the grade in my GPA?
Only if your school has a grade replacement or forgiveness policy. Many colleges replace the grade once or twice; others average both attempts. Check your registrar’s policy.
How much can retaking an F raise my GPA?
With replacement, an F to B in a 3-credit course adds 9 quality points: over 60 credits that is +0.15, over 30 credits +0.30. The fewer credits you have, the bigger the jump.
Do graduate schools see retaken grades?
Usually yes. The original grade stays on the transcript, and medical schools (AMCAS) and many graduate programs count every attempt in their GPA calculation.
Should I retake a class with a C?
Retaking a C to get an A adds 6 quality points for a 3-credit course, which matters less than retaking an F. Consider the time, cost and whether a higher grade is needed for your major.
