What is the Anna University 2025 regulation?
The Anna University 2025 regulation, commonly called R2025, is the latest academic framework for undergraduate and postgraduate engineering programmes at colleges affiliated to Anna University.
Basically, it lays down rules for the curriculum structure, credit system, exams, internal assessments, grading, GPA calculations, and finally, the degree completion.
It’s effective from the 2025 admitted batch onwards. It does not apply to students admitted under R2017 or R2021 unless Anna University officially announces so.
Key changes in Anna University R2025
- R2025 continues the Choice-Based Credit System (CBCS), giving a clearer structure to core subjects, electives, internships, and projects. These credits now clearly reflect actual workload and learning outcomes, which helps you when applying for higher studies abroad.
- R2025 gives more weightage for continuous internal assessment. So, instead of relying heavily on the end-of-semester exams, R2025 focuses more on internal tests, assignments, projects, and practical exam evaluations.
- It also has a clearer focus on programme outcomes. This means that each course is mapped to programme outcomes and learning outcomes.
- It also gives you a better integration of internships and projects, so practical exposure is encouraged earlier in the programme.
For detailed information on the courses offered and their respective credits under the new 2025 curriculum, view the complete course and credit details at Anna University’s official list of undergraduate programme structures.
This resource helps you understand how many credits each theory, lab, project, and elective carries under R2025, and how your overall academic workload is planned across semesters.

Credit system and grading under R2025
While exact credit numbers vary by programme, the core structure remains semester-based, with credits assigned for theory courses, laboratories, projects, and internships. Usually, the grades are given using a letter grade system, which is then converted into SGPA and CGPA.
How SGPA, CGPA, and percentage are calculated under Anna University R2025
Under the Anna University 2025 regulation (R2025), student performance is measured using SGPA, CGPA, and percentage, based on the Choice-Based Credit System (CBCS). Here’s how each is calculated.
SGPA (Semester Grade Point Average)
SGPA reflects your academic performance in a single semester. It is calculated as the weighted average of grade points earned in all courses registered during that semester.
Formula:
SGPA = ∑ (𝐶𝑖 × 𝐺𝑃i) / ∑ 𝐶𝑖
Where:
𝐶𝑖 = Credits assigned to a course
𝐺𝑃i = Grade points obtained for that course
n = Number of courses successfully cleared in the semester
CGPA (Cumulative Grade Point Average)
CGPA represents your overall academic performance across all completed semesters. Anna University calculates CGPA by considering the total credits and grade points earned throughout the programme.
Formula:
CGPA = ∑ (𝐶𝑖 × 𝐺𝑃i) / ∑ 𝐶𝑖
In simple terms, CGPA is the ratio of the total weighted grade points to the total credits earned across all semesters.
Percentage calculation
To calculate the percentage of marks, divide the marks obtained by the total maximum marks and multiply by 100.
Formula:
Percentage = (Obtained marks / Total marks) × 100
Example:
If you score 80 out of 100, your percentage is:
(80 ÷ 100) × 100 = 80%
This format is easily understood by international universities, especially in the UK, Europe, Australia, and Canada.

How does R2025 affect higher studies and studying abroad?
If you’re planning to study abroad, R2025 is actually helpful. The credit system is clearer, so foreign universities can easily understand what you’ve studied. Since learning is more practical and outcome-based, your marksheets show real learning, not just exam scores.
The way internships and projects are structured also helps you write a strong SOP and CV. Plus, the GPA system used in R2025 matches what most international universities already follow.
