Understanding semester-wise vs cumulative grade point averages
What is SGPA?
SGPA measures your academic performance for a single semester or term. It's calculated using only the courses taken during that specific period.
Formula:
for one semester
Key Characteristics:
- Calculated per semester
- Shows short-term performance
- Helps track progress over time
- Used for semester-wise evaluation
What is CGPA?
CGPA measures your overall academic performance across all semesters. It's a cumulative average of all courses throughout your entire program.
Formula:
across all semesters
Key Characteristics:
- Calculated across all semesters
- Shows overall performance
- Used for final transcripts
- Required for applications
To calculate your CGPA from multiple semester SGPAs, you need to consider the credits for each semester:
Step-by-Step Method:
- Multiply each semester's SGPA by the total credits for that semester
- Sum all the products from step 1
- Sum the total credits from all semesters
- Divide the sum from step 2 by the sum from step 3
Example:
Semester 1: SGPA = 8.5, Credits = 20
Semester 2: SGPA = 9.0, Credits = 22
CGPA = ((8.5 × 20) + (9.0 × 22)) / (20 + 22)
CGPA = (170 + 198) / 42
CGPA = 8.76
