Hello,

JEE is for the admission in different government as well as private engineering colleges. If you want to take admission in IITs or NITs or Gratis , then you need to score 75% in your 12th board exams or either you should be in the top 20 percentile. But if you can take admission in private engineering colleges , then you can appear in JEE without securing 75% marks in 12th boards.

Hope this will help you !
