Comprehensive Academic Grading System Guide

What is SGPA?

SGPA (Semester Grade Point Average) measures a student's academic performance in a single semester. It is computed as the weighted average of grade points earned across all registered subjects, where the weights correspond to the credit values of each subject.

SGPA = Σ(Credit × Grade Point) / Σ(Credit)

What is CGPA?

CGPA (Cumulative Grade Point Average) represents the overall academic performance across all completed semesters of a degree program. It evaluates total earned grade points against total degree credits completed so far.

CGPA = Σ(SGPA × Semester Credits) / Σ(Semester Credits)

Key Difference Between SGPA and CGPA

While SGPA focuses exclusively on a single semester's performance, CGPA provides a cumulative evaluation over your entire academic journey up to the current term.

How to Calculate SGPA & CGPA Step-by-Step

Calculating SGPA:

  1. Multiply the credits of each subject by the grade points earned in that subject.
  2. Sum up all credit points to get the Total Credit Points.
  3. Sum up all subject credits to get Total Credits.
  4. Divide Total Credit Points by Total Credits to calculate your SGPA.

Calculating CGPA:

  1. Multiply each semester's SGPA by its total semester credits.
  2. Add up these products across all semesters to obtain total weighted grade points.
  3. Divide by the total credits earned across all semesters.
