I think IIITs are good, but you need to do hard work.

Yes, of course, you can get admission.

Yes, it is necessary to give improvement exam of atleast 5 subjects to eligible for JEE. As this part is also mentioned in the JEE Mains information bulletin.

No, you may not get admission in NITs with this score if you belong to the reserve category. You can try for Thapar University, AMU, etc.

Sorry to say Naveen. By the counseling of JEE by josaa admission is possible in IITs NITs and GFTIs. So, you have to be in the merit list or your rank must be less than the closing rank of college and your rank is to high which is above the closing rank of all the college by JOSAA. So, you must try in any other counseling.

No way, you need to qualify JEE advance with a very good rank to be eligible.
