Hi apuri suresh kumar,

75 precentage must for jee.

You have to score 60% marks in Maths,Physics and Chemistry to apply for JEE Mains.

Dear Siddu,

If you want to take admission in NITs/IIITs and GFTIs you should have 75% marks in your class 12th or you should be in top 20 percentile in general category. For SC/ST it is 65% marks.

DTU and NSIT also consider JEE Main marks to provide admission. In order to be eligible you should have 60% aggregate marks in PCM in general category. There is a relaxation of marks for reserved category. 

There are many private colleges as well who consider JEE Main marks to provide admission in which there is no 75% criteria. You have to apply seperately for the application form of these colleges.

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
