Calculate your cumulative CGPA on Institute of Space Technology's own 4-point scale, weighted by credit hours. Your entries stay in your browser.
Your CGPA is a credit-hour weighted average, not a simple average of your semester GPAs.
Each course contributes grade points × credit hours (its quality points) and your CGPA is
the total quality points divided by the total credit hours attempted.
This is why a 4-credit course moves your CGPA roughly four times as much as a 1-credit lab, and why averaging your semester GPAs directly gives the wrong answer whenever your credit load varies between semesters.
IST permits absolute or relative grading at the instructor level in the cited graduate handbook. GPA/CGPA are credit-weighted and rounded to two decimals.
