Step-by-Step Worked Calculation Example
Consider an Anna University B.Tech Information Technology student completing five courses:
- 1Discrete Mathematics: 4 Credits × Grade A (8) = 32 Quality Points
- 2Design & Analysis of Algorithms: 4 Credits × Grade A+ (9) = 36 Quality Points
- 3Operating Systems: 3 Credits × Grade O (10) = 30 Quality Points
- 4Database Management Systems: 3 Credits × Grade B+ (7) = 21 Quality Points
- 5DBMS Laboratory: 2 Credits × Grade O (10) = 20 Quality Points
Sum of Quality Points: 32 + 36 + 30 + 21 + 20 = 139 Points
Total Enrolled Credits: 4 + 4 + 3 + 3 + 2 = 16 Credits
