Of course there are NCC in colleges.

Not every colleges have NCC but many of them do. You can check online about the colleges that offers NCC. It would have been better if you have mention the college you wanted or the state you are staying in. Almost 91 University across the countries have adopted and ncc.

reservation for NCC cadets in Engineering Seats, Medical Seats and Post Graduation seats are available in most of the Indian Universities.

In July, 2020, the Government has sanctioned the scheme of expansion of NCC to Coastal/Border talukas with the strength of one lakh cadets.  The scheme is to expand the NCC Cadet base in 172 border Taluks, 92 coastal taluks and 43 major Air Force Stations.

There are government and private colleges which has NCC. But students studying in colleges not connected with NCC also can join NCC. Students get B.Tech seats based through NCC Quota. from the colleges you will be able to get C certificate after the examination and training. You are eligible for that only if you have already got A and b certificate. A and b certificate are supposed to get from your school time.

It would have been a lot better if you have mention the college you want. Because almost every colleges in India has NCC NCC you don't have to worry about that.

Thank you
