Pradeep,
There will be no problem in admission in NITs. If you drop for JEE, but if you are getting B.Sc. in DU or any other prestigious universities (specially govt.) then you should choose between B.Sc and dropping wisely. Please ask yourself a question that whether you are confidence about dropping or not and is it you who wants to an engineer or everybody else except you. Ask these two questions before dropping.
If you are confident enough then dropping is the best option for you.

You can. If you did not opt for maths in 12. However, subjects like chemistry and physics have essence of Maths. Also, if you are running away from maths, you can be botanical scientists.

If it is GATE rank, you may get a seat in NITs or in any other deemed universities.
