Hello,

The eligibility requirements for JEE Advanced 2022 have been loosened, allowing applicants who were unable to sit for the exam in 2020 to 2021 to sit for it this year. The 75% threshold for JEE Advanced eligibility had previously been eliminated, as it had the year before. According to this requirement, a candidate must have obtained at least 75% of the total possible points on their class 12 (or equivalent) board exam, or they must have placed in the top 20 percent of all successful applicants.

So, you got 76% in 12th then you are eligible to apply for JEE Advance to get seat in IIT.
