Overview of Anna University Grading System (R2021 and R2017)
Anna University (AU Chennai) is one of the premier technical universities in South Asia, governing over 500 engineering institutions across Tamil Nadu including the College of Engineering Guindy (CEG), Madras Institute of Technology (MIT Chromepet), and Alagappa College of Technology (ACTech).
Under the Choice Based Credit System (CBCS) implemented through Regulation 2021 (R2021) and Regulation 2017 (R2017), student performance in B.E., B.Tech, M.E., M.Tech, and MCA programs is evaluated using a 10-point letter grading system. When applying for public sector undertakings (PSUs), government examinations (TNPSC, UPSC, SSC), Chennai IT campus recruitments, or higher education admissions abroad, converting your cumulative grade point average into a certified percentage is an essential administrative requirement.

Official Anna University CGPA to Percentage Formula
According to official circulars and academic ordinances issued by the Syndicate and Controller of Examinations (COE) of Anna University, the percentage conversion follows a direct, standardized multiplier of 10:
Unlike universities that subtract an offset factor (such as AKTU and VTU subtracting 0.75, or KTU using 10 × CGPA - 3.75), Anna University maps the 10-point scale directly onto the 100-percent scale.
• 8.75 CGPA = 8.75 × 10 = 87.50% (First Class with Distinction)
• 7.50 CGPA = 7.50 × 10 = 75.00% (First Class)
• 6.00 CGPA = 6.00 × 10 = 60.00% (Standard IT Campus Placement Cutoff)
10-Point 8-Grade Scale Matrix Table (O, A+, A, B+, B, C, U)
Under Anna University Regulation 2021, absolute marks scored in continuous internal assessments and end-semester examinations are converted into letter grades and grade points:
| Letter Grade | Grade Points | Marks Range (%) | Performance Description |
|---|---|---|---|
| O | 10 | 91 - 100 | Outstanding |
| A+ | 9 | 81 - 90 | Excellent |
| A | 8 | 71 - 80 | Very Good |
| B+ | 7 | 61 - 70 | Good |
| B | 6 | 50 - 60 | Average |
| C | 5 | 45 - 49 (R2017) / 50 (R2021) | Satisfactory / Minimum Pass |
| U | 0 | < 50 | Re-appear (Arrear) |
| SA / W | 0 | Shortage / Withdrawn | Shortage of Attendance / Withdrawal |
8-Semester Credit-Weighted SGPA to CGPA Accumulator Algorithm
In engineering programs, CGPA is not a simple arithmetic average of semester SGPAs because different semesters carry varying credit weights. The exact cumulative performance is computed using the credit-weighted summation:
Where C_i denotes total credits earned in semester i, and SGPA_i is the Semester Grade Point Average. A standard 4-year B.E./B.Tech curriculum under Regulation 2021 totals approximately 160 to 165 credits.
Degree Classifications (First Class with Distinction, First Class, Second Class)
Anna University awards final degree certificates with specific classifications based on merit and completion timeline:
- First Class with Distinction (FCD):
- Candidate must secure a CGPA ≥ 8.50 (or 85.00%).
- Must pass all subjects in the very first attempt (zero arrears) throughout all 8 semesters.
- Must complete the degree within the normal period of 4 academic years (3 years for lateral entry).
- First Class:
- Candidate must achieve a CGPA ≥ 6.50 (65.00%).
- Must complete the degree within a maximum of 5 academic years (4 years for lateral entry).
- Second Class:
- All other candidates who qualify for the degree with CGPA ≥ 5.00 but do not satisfy First Class criteria.

Step-by-Step Solved Student Examples (B.E. and B.Tech)
Example 1: B.E. Computer Science Graduate (Direct CGPA)
A student from CEG Guindy graduates with a final CGPA of 8.64 without any arrears.
Calculation: 8.64 × 10 = 86.40%
Classification: First Class with Distinction (FCD) (CGPA ≥ 8.50 and 0 Arrears).
Example 2: Reverse Conversion for PSU Recruitment
A B.Tech Mechanical graduate needs to enter equivalent CGPA for a PSU application requiring 65.00% marks.
Calculation: 65.00 / 10 = 6.50 CGPA
Classification: First Class.
Frequently Asked Questions (FAQs)
According to official Anna University regulations (Regulation 2021, Regulation 2017, and Regulation 2013), the conversion formula is: Percentage = CGPA × 10. For example, a CGPA of 8.25 equals 82.50%.
Under Anna University Regulation 2021, a student must secure a CGPA of 8.50 or above, pass all subjects in the very first attempt (zero arrears), and complete the B.E./B.Tech degree within the stipulated 4 years (8 semesters).
To secure First Class in Anna University, a candidate must obtain a CGPA not less than 6.50 and complete the degree program within a maximum of 5 years (for 4-year B.E./B.Tech).
CGPA is calculated using the credit-weighted average: CGPA = Σ(C_i × SGPA_i) / Σ(C_i), where C_i represents the credits assigned to semester i and SGPA_i is the Semester Grade Point Average.
In Regulation 2021, 'C' is the minimum passing letter grade with 5 grade points (50% marks). Any score below 50% or non-appearance is marked as 'U' (Re-appear) with 0 grade points.
Mass recruiters like TCS, Cognizant, Wipro, and Infosys require a minimum of 6.00 CGPA (60%) with no standing arrears. Product companies such as Zoho, Amazon, Microsoft, and PayPal typically set their initial cutoff at 7.50 to 8.00 CGPA.
