Hii

Minimum percentile for cracking jee mains is 87 percentile. But some other institutes also said that, those who have more than 82 percentile can also eligible for jee adavnce. But according to my opinion, 87 percentile is minimum for cracking jee mains. If you have more than 42 marks in jee mains, that means you will be eligible for jee advance. But just wait for official rank which will be announce soon by NTA.

Hope this information is helpful for you.
