University Departments versus affiliated colleges
Anna University examines both its campus departments and a large set of affiliated colleges. The July 2021 letter is from ACOE (University Departments). If you studied at CEG, MIT, ACT, or another University Department under R2015 / R2018 / R2019 as listed, × 10 is the formula in that letter. If you studied at an affiliated college, ask that college’s exam cell before using this page on a job form.
We do not list affiliated-college R2021 or other regulations here. Those need their own verified circulars.
What × 10 means in practice
A 7.00 CGPA is 70.00%. A 8.50 CGPA is 85.00%. There is no 0.75 or 0.5 offset in this letter. Mixing in a VTU-style subtraction would understate the University Departments figure.
Worked examples
- CGPA 6.00: 6.00 × 10 = 60.00%
