NIT

Hello niharika. There are lots of NITs and each has different cutoff ranks for different branches. So whether or not you'll get admission in one depends upon which state you belong to, which state you want to take admission in and what branch you want.
You can check you expected rank here:

Apart from NITs, there are other colleges that take admission through JEE mains score, like DTU, NSIT, Jamia Milia, Jaypee etc. Or else you can take other tests like bits, Manipal, srm, IPU etc to get admission into these colleges.

If you are in general category sorry Hitesh you cannot get admitted in NIT coz minimum number needed in JEE main for NIT is 200 .
But you can try for other private colleges or universities.
Best of luck

DEPENDS ON YOUR JEE ADVANCED MARKS.

DEPENDS ON YOUR 12TH MARKS AND THE MARKS U WILL GET IN JEE ADVANCED

Hi Gaurav. I would most definitely recommend you to prepare for exam of private universities. You have Bits, indraprastha university, Vellore, Manipal, srm and such good colleges that don't consider JEE score but take their own respective entrance tests. These colleges have best teaching faculties as well. I would not recommend dropping a year. You may have to explain your decision of dropping at the time of placements and also at the time of interview if you decide to go for higher education especially MBA. Instead prepare for the private university tests. All the best!

Look for it in information brochure, you can easily find it there.

sorry but No NIT is open for you .For NIT your marks in mains must be above 200.

Yes, you have chances.
