Calculate your cumulative CGPA on Pakistan Institute of Engineering and Applied Sciences'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.
BS rules explicitly use a 4-point scale; subject, semester and degree passing thresholds are separately defined. Percentage bands come from Table 2 of the PIEAS BS academic rules. A mark of 45 to 49 earns GP 1.0 and counts toward the GPA, but the course must still be repeated to reach the C grade needed to pass.
