| Programming | 3 | O | 10 | 30 |
| Lab | 2 | B+ | 7 | 14 |

📈 How to Improve GPA at Anna University
- Focus on High-Credit Subjects: A 4-credit subject has double the weight of a 2-credit lab. Scoring 'O' in a 4-credit course boosts GPA significantly.
- Avoid Arrears (RA): RA subjects add credits to the denominator but give 0 points to the numerator, pulling GPA down heavily.
- Improve Internals: High internal assessment scores reduce the pressure on end-semester exams.
📉 Common GPA Calculation Mistakes
- Ignoring subject credits (treating all subjects as equal weight).
- Using percentage instead of Grade Points for calculation.
- Including failed subjects incorrectly (forgetting that they still count as attempted credits).
- Mixing Regulation 2017 rules with Regulation 2021 grading.
