Hii..

For the candidates to qualify for the admission in the IITs/NITs/IIITs and such other CFTIs whose admissions are based on the JEE (Advanced)/JEE(Main) ranks, they should have secured at least 75% marks in the 12th class examination, or be in the top 20 percentile in the 12th class examination conducted by the respective Boards. For SC/ST students the qualifying marks would be 65% in the 12th class examination

Hello Sanjana. As it stands presently, the current cutoff for Maths required for JEE Advanced is 75% for General / OBC and 65% for the Reserved Castes. 

Hi,

For General/OBC it is 75% and for others it is 65%.

You can refer the Career360 page for the details.But as for now minimum 75% is required for JEE exam.
