Can we also go to schools and tuitions during NCC training period after 10th?
Ofcourse you can go with your academic activities along with NCC activities
You can see NCC Colleges in Kerala (https://coursesinkerala.in/ncc-colleges-in-kerala-2021/) here
hi....
You can join NCC after class 10 , the college or school in which you get admission should have NCC Unit in which you can join . Otherwise, If your school doesn't have NCC unit and you are really inspired to join NCC then you can join it by open cadet entry by contacting to your nearest NCC Headquarter.
