Frequently Asked Questions
How is CGPA calculated?
CGPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours). Multiply each subject's GPA points by its credit hours, add them all up, then divide by total credit hours. Our calculator does this automatically.
How do I convert marks to CGPA in Pakistan?
First convert marks to percentage (obtained ÷ total × 100). Then look up the HEC grading scale: 90%+ = A+ (4.0), 85-89% = A (4.0), 80-84% = A- (3.7), 75-79% = B+ (3.3), 70-74% = B (3.0), and so on. Our Grade Checker tab does this instantly.
What is a good CGPA in Universities?
3.7–4.0 = Distinction (Dean's List), 3.0–3.69 = Very Good, 2.5–2.99 = Good, 2.0–2.49 = Satisfactory, below 2.0 = Academic probation risk.
What is relative grading and how is it calculated?
Relative grading scales your marks based on the class topper. Formula: Scaled % = (Your Marks ÷ Highest Marks) × 100. If highest is 70 and you got 56, your scaled score = 80%. This is used when papers are harder than expected.
How do I calculate cumulative CGPA across semesters?
Cumulative CGPA = (Previous CGPA × Previous Credits + Current GPA × Current Credits) ÷ Total Credits. Use our CGPA calculator — enter current semester subjects plus your previous CGPA and credit hours to get the exact cumulative figure.

Does this calculator support Pakistani and US grading systems?
