Policy note: Repeating a course does not guarantee a higher official GPA. Verify eligibility, attempt order, petitions, limits, and transcript treatment first.
Repeat rules are more than “replace or average”
A policy may:
- include all attempts as separate credit-weighted rows;
- exclude a specified earlier attempt after an approved petition;
- replace attempts only within a unit or course limit;
- change treatment for later attempts;
- prohibit repeating an already-passed nonrepeatable course; or
- treat repeatable-for-credit courses separately.
Do not average two letter-grade values before accounting for their credits. Do not assume degree credit is earned twice merely because two attempts enter GPA.

Three policy architectures
UC Davis: limited replacement, then include all
UC Davis permits undergraduates to repeat and replace up to 16 eligible units under specified conditions. Within the limit, the later attempt is included and the earlier attempt excluded from GPA. After the limit, all grades and attempted units are included. Degree credit is awarded once, and assigned grades remain on the transcript.
Second or later repeats require approval.
Ohio State: default repeat versus requested forgiveness
Without grade forgiveness, Ohio State keeps both grades in cumulative GPA while degree credit counts once. Grade forgiveness requires a request, replaces the first attempt's grade and hours in the Ohio State GPA with the second attempt, and is limited by course and use rules.
The second grade remains even if lower. The original grade remains visible, and forgiveness does not retroactively review academic standing.
Stanford: later attempts have distinct treatment
Stanford waits for final grades before repeat processing, distinguishes W from a completed attempt, and imposes conditions for a third enrollment. After a third completion, specified later grades and units enter cumulative GPA. Duplicating external credit can also remove the external units.
These are named institutional examples, not a national taxonomy.
Scenario arithmetic
For the policy-approved attempt set:
scenario GPA = sum(grade points for attempt × GPA-bearing credits for attempt) ÷ sum(GPA-bearing credits for included attempts)
Useful labels are:
- include-all hypothetical;
- exclude-specified-attempt hypothetical; and
- official GPA only after the posted transcript confirms it.
A retake GPA calculator can compare these scenarios. It does not approve a repeat or forgiveness request.
Separate consequences
GPA inclusion, earned degree credit, transcript history, academic standing, honors, aid, licensure, and application-service recalculation are separate questions. An external application may count attempts differently from the home institution.
Bottom line
Translate the exact repeat policy into included and excluded rows before recalculating. Attempt limits and petitions can change the result, and a lower later grade can reduce GPA. Keep every scenario hypothetical until the official record posts.
