I got compartment in maths in class 12 2017 than I gave failure exam in 2018 but still I got a compartment in maths again.what should I do?
Thing is, (as far as Google knows), every college needs you to pass out of 12th. If you qualify for counselling after JEE Mains, (or any other exam which is succeeded by counselling), then you should be fine if you can clear NIOS and show your papers to the counselling committee. Otherwise, you either have to repeat or drop out.
Good Luck! Hope you get what you want!
