Dear Aspirant,

No IIT do not have any weightage for the +2 marks, however, you have to have a minimum 75% marks in CBSE board or be in the top 20 percentile of your respective board to be eligible for the admission in the IITs and NITs.

Generally, there is no weightage for the+2 marks in engineering colleges, but they mostly have some minimum eligibility criteria ranging from 60-75% marks in +2.

Hope this helps. Thank you.
