Enter current CGPA, credits, old and new grades, and a retake policy to estimate your updated cumulative GPA after repeating a course.
Six common policies: highest attempt counts, latest attempt counts, average of attempts, replacement, both attempts count, and no change — matching the most common university rules.
It varies by institution and sometimes by program. Check your official registrar policy, or use the International Systems directory to confirm a verified policy before relying on the result.
Usually, but not always by as much as you'd expect. Under a replacement or highest-attempt policy the old grade drops out entirely, but under an average or both-count policy the original grade still partly counts.
