Under the Choice Based Credit System (CBCS) introduced by the University Grants Commission (UGC) and All India Council for Technical Education (AICTE), college examinations no longer award simple percentage aggregates. Instead, student transcripts report performance via SGPA (Semester Grade Point Average).
SGPA is the weighted average of the grade points obtained in all subjects registered by a student during a single semester:
Where:
| Letter Grade | Description | Grade Points ($G_i$) | Typical Marks Range (%) |
|---|---|---|---|
| O / S | Outstanding | 10 | 90% to 100% |
| A+ | Excellent | 9 | 80% to 89% |
| A | Very Good | 8 | 70% to 79% |
| B+ | Good | 7 | 60% to 69% |
| B | Above Average | 6 | 55% to 59% |
| C | Average | 5 | 50% to 54% |
| P | Pass | 4 | 40% to 49% |
| F / Ab | Fail / Absent | 0 | Below 40% |
| Subject | Credits ($C_i$) | Grade | Points ($G_i$) | Credit Points ($C_i \times G_i$) |
|---|---|---|---|---|
| Mathematics III | 4 | A | 8 | 4 × 8 = 32 |
| Data Structures | 4 | A+ | 9 | 4 × 9 = 36 |
| Digital Electronics | 3 | O | 10 | 3 × 10 = 30 |
| Microprocessors | 3 | B+ | 7 | 3 × 7 = 21 |
| Data Structures Lab | 2 | O | 10 | 2 × 10 = 20 |
| TOTALS: | 16 Credits | - | - | 139 Points |
SGPA = 139 ÷ 16 = 8.6875 (~8.69)
Percentage = (8.69 - 0.75) × 10 = 79.40% (First Class with Distinction)
Different educational boards and autonomous universities apply specific conversion formulas for campus placements and government recruitment applications:
Percentage (%) = (SGPA - 0.75) × 10. E.g., an 8.0 SGPA = (8.0 - 0.75) × 10 = 72.5%.Percentage (%) = SGPA × 10. E.g., an 8.5 SGPA = 85.0%.Percentage = 7.1 + 7.4 × (SGPA - 7).CGPA = Σ(SGPA_i × Credits_i) ÷ Σ(Credits_i). If all semesters have identical credit totals, CGPA is simply the arithmetic average of your SGPAs.
(SGPA - 0.75) × 10 formula to standardize the conversion between relative grading on a 10-point scale and traditional percentage marks. This ensures that an SGPA of 6.75 corresponds cleanly to the traditional 60% First Class milestone.
