Hello,

Yes, you will be eligible to give JEE Mains exam and JEE Advanced. The criteria to give JEE mains exam is not top 20 percentile or 75% aggregate. You can still give JEE mains even if you are not able to score 75% in your 10+2 level or even if you are not in the top 20. The minimum 75% aggregate was for admissions in NITs and IITs which the officials have removed due to the COVID situation.  Top 2,50,000 successful candidates on the basis of JEE Main 2022 exam will be eligible to attempt the JEE Advanced exam.
