Hello Dear

Inorder to join the NCC from any of the respective college you have to first participate in the competition which the NCC usually used to conduct for taking the candidate's like running, push ups, pull ups and all and based upon the selection process of them you can be able to enter in it either in Army, Navy or in Air force.

All the best

Hi AJWED
ACE college of engineering does not have NCC.If you are already enrolled in the college then you can join Ncc as open candidate. It means you have to attend Ncc in other colleges.
Procedure of joining
1. Find the nearest NCC battalion
2. Ask the subedar major of that battalion for the application
3.if you are eligible then he will assign you a ncc battalion for training . In some othwr colleges of same university.
4.if there are no vaccancies in any other colleges then they may train you in Ncc head quaters.
This is how it works.
Hope it helps
