Hello dear student,

Every student aspiring for admission to an IIT has to first appear for the JEE Main Examination. Once qualified, he/she has to appear for JEE Advanced Examination. ... Those who clear JEE Mains only are eligible for admission to NITs, IIITs, CFTIs, SFIs, and State Engineering Colleges (for some States).

While it's difficult to predict that you can get into IIT with 90 marks . Kindly mention your category also and without category it cannot be decided.

Thank you
