Yes ,there is an exservice men quota in Anna University . However ,the number of seats through this quota are very limited.At the time of counselling you will have to submit the required documents and Id card of your parent ,i.e their ex servicemen Id card.

2.The counselling procedure for CBSE students and state board is same.But ,cut off marks is calculated differently.

Example

The maximum mark in CBSE exams is 100. Let's assume, that the top mark in Maths is X, Physics is Y and Chemistry is Z. If the candidate scores A/100 in Math, B/100 in Physics and C/100 in Chemistry, then the cut-off is calculated as (A/X)*100 + (B/Y)*50 + (C/Z)*50.

All the best
