SGPA measures performance within one semester, while CGPA summarizes performance across multiple semesters. Both values are useful, but they answer different academic questions.
SGPA focuses on one term
Semester Grade Point Average helps you understand how you performed during a specific academic term. It is useful for tracking improvement, identifying weak semesters, and estimating how a recent result affects your overall record.
CGPA shows the cumulative picture
Cumulative Grade Point Average combines semester performance into a single number. Universities often use CGPA for eligibility, scholarships, placements, and academic progression.
Why calculation rules differ
Some institutions use a simple average of semester GPAs. Others use credit-weighted calculation, where semesters with more credits have more influence. Always confirm the official method with your institution.
