Hi,

You can appear for JEE Mains examination after passing class 12 examination from a recognised board. However, for admission into NITs, IITs, GIFTs, etc. Candidates must have to score 75% in aggregate in class examination or must be in top 20 percentile in class 12 examination. This rule was relaxed for the year 2020 seeing amid the COVID 19. You can check the complete information over here: https://engineering.careers360.com/articles/jee-main-eligibility-criteria

There's no percentage barrier to be eligible for JEE mains.

For example,

Eligibility criteria says that to be eligible  for JEE mains 2021 for BE or Btech you should be either appearing for 12th board exam or equivalent  in 2021 or should have passed it in 2020 or 2019 with Physics,  mathematics and anyone of Chemistry or Biology or Biotechnology or Technical Vocational Subject.

So, there is no requirement of minimum percentage to be eligible for JEE Mains
