Yes,Ncc certificate is useful while allotting seats in eamcet based on ncc quota. According to ranks, you need to take ncc certificate with you.

Hi aspirant,

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 less value except for providing grace marks in SSLC. There is exam conducted for B certificate. 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.
