The Controller of Examinations (COE) portal is Anna University's official hub for everything exam-related. Here's what each part is for and how to use it smoothly.
What the COE portal is for
- Results — check UG/PG semester results by register number.
- Revaluation & photocopy — apply and pay online in the announced window.
- Grievance — raise result/data issues.
- Notifications — official exam announcements.
The addresses
The main portal is coe1.annauniv.edu, with coe2.annauniv.edu as a mirror used when traffic is high. Always use these official addresses — not look-alike third-party sites.
Tips to avoid getting stuck
- Keep your register number and date of birth handy.
- On results day, use the mirror or try during off-peak hours.
- Note application windows for revaluation — they are short.
🔗 Official portal: coe1.annauniv.edu (mirror coe2) for results & revaluation · annauniv.edu for timetables & calendar. This guide explains the process — the university's site is the source of truth for live dates.
