CGPA stands for Cumulative Grade Point Average. It represents your overall academic performance across multiple semesters or subjects.
For example, if a subject has a grade point of 8 and 4 credits, its contribution is 8 ร 4 = 32 grade points.
SGPA stands for Semester Grade Point Average. It measures your academic performance for a particular semester.
Higher credit subjects have a greater effect on your SGPA because their grade points are weighted by credits.
Percentage tells you how many marks you obtained compared with the total marks available.
Example: If you score 420 out of 500, your percentage is 84%.
Your attendance percentage is based on the number of classes you attended compared with the total classes held.
