Frequently Asked Questions
What is the main difference between GPA and CGPA?
GPA (Grade Point Average) measures academic performance in a single semester or term. CGPA (Cumulative Grade Point Average) is the combined weighted average of all semesters completed in a program.
How do I convert a 10.0 scale CGPA to a US 4.0 GPA scale?
To convert a 10.0 scale CGPA to a US-standard 4.0 scale, divide your CGPA by 10 and multiply by 4 (e.g. 8.0 CGPA divided by 10, multiplied by 4 equals a 3.2 GPA).
Why do subjects have different credits in CGPA calculations?
Course credits represent the academic weight or contact hours of the subject. A core 4-credit course affects your final CGPA more than a 1.5-credit practical laboratory, ensuring your grade average reflects the relative complexity of each course.
