Your SGPA from your results
Paste your Anna University result table, or type each subject’s grade and credits.
Each line needs a Anna University grade (S, A+, A, B+, B, C, U, SA) followed by its credits, which is how result pages list them. The subjects go into the SGPA calculator below, where you can check and correct every row. Paste several semesters together to get your CGPA.
Official source: Anna University B.E./B.Tech Academic Regulations 2023, Revision 1 (official PDF). SGPA = Σ(credits × grade points) ÷ Σ credits. Grade points: the Regulation 2023 grading table. Last checked 22 September 2026. Enter every semester’s subjects together and the same sum gives your CGPA. The percentage next to it applies the CGPA formula to a single semester, so read it as an estimate.

Marks you need to pass
How much you need in the end exam, given your internal marks.
| Grade | Total needed | Exam marks needed |
|---|
Official source: Anna University B.E./B.Tech Academic Regulations 2023, Revision 1 (official PDF). Clause 17.23(i) of Regulation 2023: at least 45% of the end-semester exam and 50% of the combined total. The 40 : 60 theory split is in Table 10 (clause 17.22). Last checked 22 September 2026.
The exam minimum never moves: good internals lower what you need only down to that floor. This regulation sets no separate minimum for internals, so low internals alone do not fail the subject here.
Attendance
Whether you can still sit the exam, and how many classes you can miss.
Official source: Anna University B.E./B.Tech Academic Regulations 2023, Revision 1 (official PDF). Attendance rules: clauses 11.1, 11.2 and 11.4 of Regulation 2023. Anna University needs 75% in each course. It has no fee-based condonation: at 65% or above, absence during a medical emergency can be left out if a certificate is submitted in time. Without that, a student below 75% cannot sit that course’s end-semester exam. Last checked 22 September 2026.
Where condonation exists, it is a request your college makes for stated reasons — not something you are owed. If you land in the middle band, raise it with your college straight away.
