Hello Priyanka,

Without a college, it is impossible to join NCC.

The National Cadet Corps (NCC) is an organisation that promotes youth development. It gives the country's kids opportunity for all-round growth, instilling in them a feeling of duty, commitment, leadership, discipline, and moral values.

If your college or institution does not offer NCC, you can join NCC at another college by submitting all of the required documentation and joining as an open cadet.

Open cadets are typically assigned to another college within the same university that offers NCC, or you will have your NCC drills and training in that battalion, depending on the amount of vacancies available. If you are accepted, the college will conduct a physical efficiency exam, a written test, and maybe an interview based on their selection criteria.
