Estimate gpa after course repeat using clear inputs and transparent formulas, with results intended for planning and comparison.
How to use this calculator
For gpa after course repeat calculator, enter Current GPA, Completed credits before repeat, Previous course grade, Repeated course grade, the remaining displayed fields using the unit or format beside each field. Select Calculate to apply the formula below, review all returned values together, and use Reset to restore the demonstrated inputs before testing another scenario.
Formula & calculation method
newGpa = (currentGpa*completedCredits-oldGrade*courseCredits+newGrade*courseCredits)/completedCredits; gpaChange = (newGrade-oldGrade)*courseCredits/completedCredits; qualityPointChange = (newGrade-oldGrade)*courseCreditsWorked example
For a reproducible gpa after course repeat calculator example, use Current GPA: 3.5; Completed credits before repeat: 60; Previous course grade: 1; Repeated course grade: 4; plus the remaining displayed defaults. The first returned value, gpa after replacing previous grade, is calculated with (currentGpa*completedCredits-oldGrade*courseCredits+newGrade*courseCredits)/completedCredits; the other results describe the same scenario. Change one input at a time and keep its unit consistent when comparing scenarios.
Limitations to keep in mind
Check the input ordering and physical validity of the entered values. A mathematically finite output may still be unsuitable when efficiencies, loads, dimensions, or ratings are inconsistent.
