CGPA and aggregate calculators
Which tool to use when
You want your semester GPA or CGPA: use the HEC GPA and CGPA Calculator. Enter each course's credit hours and grade. It gives your semester GPA and CGPA on HEC's points, handles W, pass/fail and repeated courses, and shows what HEC's table gives as a percentage.
You want your MBBS or BDS aggregate in Punjab: use the MDCAT Aggregate Calculator. Enter your SSC, HSSC and MDCAT marks. It uses the UHS formula for session 2025-26, 10% SSC, 40% HSSC and 50% MDCAT, checks the minimums and shows the MDCAT marks you need for a target.
You want to know what a grade or CGPA means: see the HEC Grading Scale. It has HEC's semester and annual-system tables with their grade points and percentages.
You want your CGPA as a percentage: read HEC CGPA to percentage. It explains HEC's table, why a 3.47 is 80% and not 86.75%, and what HEC's 2008 notification says.
Guides
- HEC CGPA to percentage: how the rule works: the table, worked examples and HEC's 2008 notification.
- UHS merit list explained: the order of merit, college-wise selection and up-gradation lists for Punjab MBBS and BDS, with worked aggregates.
Tools that work with any marks
Some GradeCat tools work on marks from any country. The Grade Calculator adds up marks out of their totals, the Weighted Grade Calculator combines parts such as quizzes, a mid-term and a final with their weights, and the Final Grade Calculator shows what you need in the final. Their letter grades follow US scales, so read the percentage they give.
