Let’s get started!
CGPA stands for Cumulative Grade Point Average. It is a standardized way to represent your overall academic performance in Anna University. Instead of showing marks as percentages, the university assigns grade points for each subject based on your scores and then calculates an average weighted by credits.
Anna University uses a letter grade system along with grade points to evaluate your performance. Each grade corresponds to a range of marks and a specific grade point.
Grade | Marks Range (%) | Grade Points |
O | 91 – 100 | 10 |
A+ | 81 – 90 | 9 |
A | 71 – 80 | 8 |
B+ | 61 – 70 | 7 |
B | 51 – 60 | 6 |
C | 41 – 50 | 5 |
P | 35 – 40 | 4 |
F | Below 35 | 0 |
Every subject is assigned a certain number of credits based on its importance and workload. For example, a core subject might have 4 credits, while a lab might have 2 credits. The grade points you earn in each subject are multiplied by that subject’s credits to get weighted grade points. This system ensures subjects with more weightage impact your CGPA accordingly.
Calculating your CGPA is straightforward once you know your grade points and credits for each subject.
Subject | Credits | Grade Points | Weighted Grade Points (Credits × Grade Points) |
Maths | 4 | 9 | 36 |
Physics | 3 | 8 | 24 |
Chemistry | 3 | 7 | 21 |
English | 2 | 8 | 16 |
Computer Sci | 4 | 10 | 40 |
Total | 16 | — | 137 |
CGPA = Total Weighted Grade Points ÷ Total Credits = 137 ÷ 16 = 8.56
