Hello,

So, basically if you have an NCC certificate then you can take its benefit in EAMCET reservation.
The NCC certificates are divided into A, B and C certificates. NCC A certificate is given at school level. NCC B is achieved in class 12th with 75% marks and a camp if you have participated. NCC C certificate is given to a candidate having B certificate and if the student has either been a part of any outdoor camp or Republic day parade.
The NCC A certificate has slight less value. For B certificate there is an exam conducted. If you qualify, you will attain a C certificate which is actually important. However, NCC certificates are accepted by EAMCET counselling. The first priority is given to NCC C, followed by B then A.

I hope this helps.
