Hello,

Minimum eligible criteria for JEE Main -

1. Three consecutive tries at JEE Main are the most that students may make. The first attempt is made shortly after the 12th grade board exams, and the subsequent tries are made in succeeding years. There will be two exam dates per year, making a candidate eligible for a total of six appearances.
2. A candidate may apply for the JEE Main exam if they hold a diploma. The rank and exam score, however, will not be taken into consideration for admission to NITs or CFTIs.

So, as per eligibility criteria, you are eligible for JEE Main but you will not able to take admission in NITs or CFTIs.

Thank You
