CGPA Scale Comparison
Choose the scale used by your school. Incorrect scale selection is one of the most common CGPA errors.
| Scale | Common Usage | Maximum | Quick Formula |
|---|---|---|---|
| US 4.0 | Most US colleges and universities | 4.0 | Percentage ≈ (CGPA ÷ 4.0) × 100 |
| Canadian 4.3 | Many Canadian institutions | 4.3 | Percentage ≈ (CGPA ÷ 4.3) × 100 |
| Indian 10.0 | India and many international institutions | 10.0 | Percentage ≈ CGPA × 9.5 |
Prioritize High-Credit Courses
A grade improvement in a 4-credit course influences CGPA more than a 2-credit course. Plan your effort where impact is highest.
Track Trend by Semester
Admissions teams care about trajectory. A consistent upward semester trend can strengthen applications even if starting CGPA was lower.
Use Scenario Planning
Simulate upcoming terms in the calculator to set realistic grade targets before registration or finals week.
