Hello,

Those are already appearing for 12th class and those are passed in 12th class, they are eligible for given JEE main examination. If you give JEE mains examination in your 11th standard but you can't take admission after getting your 12th mathematics result. So i will suggest you can give mock test for this examination in so many institutions or free online mock test are available. You can go for previous year JEE mains questions solve procedure. And give JEE Mains examination 2022. It will be best for you.

All the best.
