NIT

Hello Saurabh,
You have asked an existential question. Answer unfortunately is straight forward no. Other institutions which take score from JEE Mains do accept lower scores, but these too have already been announced. You definitely need to score 75% or more in your boards to get into IITs.

Hello Hasnain,
With only 108 marks in JEE Mains, you would have cleared cutoff but still long way off towards getting admission. Remember marks are out of possible 360.

No, everything is done on the basis of JEE Mains.

Yes, you can do that.

You can join NIT. If you are confident, then you can prepare it along with your college.

No, regular candidates should possess a valid score in the Common Admissions Test (CAT) conducted by the Indian Institutes of Management. IIT graduates, who obtain a CGPA of 8 and above on 10 are exempted from CAT score. Their shortlisting will be based on a composite score with due weights to applicant CAT score, past academic performance, industry experience and gender.

For CBSE, its 75% and for other state boards, it varies.

In order to get in IITs, you need to qualify in JEE (Mains) & then JEE (Advance). Start preparing now. It's tough but not impossible.
All the best.
