JEE Main

Hello, hope you are doing well.
No, you need to score 75% in 12th class. Then only you will be eligible to get the JEE Advanced colleges. If you will give the exam of JEE next year, this issue will still persist. Go for JEE Mains counselling. With this rank, you will get a great college.
Don't go for drop as this will waste your time for 1 year.

Yes, all the colleges which take through JEE Mains score by JoSAA counselling.

You have minimum marks in JEE Mains. You cannot get NIT.

It's only depending on your college. You can try in private colleges.

Congrats for this rank. It seems difficult to get any NITs or IIITs. But you can get good state government colleges in other states on this rank. Good luck.
