Formula: New CGPA = (Current × Total + (New GP − Old GP) × Credits) / Total Credits
📐 Formula
New CGPA = (Current Pts + [New GP − Old GP] × Credits) / Total Credits- Enter your Current CGPA and Total Credits — multiplying them gives your current grade points.
- Add each subject you plan to improve with its current grade, target grade, and credits.
- For every subject, the gain is (target grade point − current grade point) × subject credits.
- The gains are added to your current points and divided by your total credits to give the projected new CGPA.
📈 Grade Improvement
Retaking a subject through a grade-improvement exam replaces the old grade point with the new one, and because the calculation is credit-weighted, the same jump in grade moves your CGPA further in a high-credit subject than in a low-credit one. Improving an F (0) to a B+ (7) in a 4-credit course, for example, adds far more to your total grade points than the identical improvement in a 1-credit lab.
This calculator is built for the decision itself: is the improvement exam worth the time and fees? Enter the subjects you are considering and it quantifies the exact CGPA delta before you commit — so you can prioritise the retakes that genuinely move your score and skip the ones that barely register.
❓ Frequently Asked Questions
Can I improve after graduation?
Generally no — grade improvement exams must be completed while you are still enrolled as a student, so plan any retakes before your degree is awarded.
