IIT

Hello, As per your mentioned question, there are no IITs which give admission just by opting JEE Mains exams, but for NIT, you have to clear JEE Mains. You have to clear both JEE Mains as well as JEE Advanced. Also, you have to score well in JEE Mains to get a good NIT.

The package varies from Rs.10 Lacs to Rs.50 Lacs.

Hi Mithuna,
Yes, there is gain in doing M.Sc in IIT. It opens up more job and fellowship opportunities for after M.Sc, as government provides many fellowship schemes to students who have studied in IIT. Good luck.

I'll prefer you to join any other coaching institute like Allen and Resonance as the coaching institute mentioned by you is also quite good. But the main problem is that their passing ratio is not that good.

I'll suggest you to opt for FIITJEE as this coaching institute has good faculty and also has the easiest way to teach students the most difficult questions.
