Shreyas, the cutoff of JEE Mains will be released along with the final results once the April session is conducted. Then NTA will announce the category wise qualifying cutoff for JEE Advanced which will be displayed on the result portal.

The cutoff percentile is expected to change every year depending on the number of seats available and the number of students appearing. While it is difficult to predict the exact qualifying cutoff, a percentile of 85 or above is decent enough to qualify for JEE Advanced. You can also go through the previous years' cutoff to get an idea. In 2019, the NTA score cutoff for the Common Rank List was 89.7548849

According to your total score, it might be difficult to clear the cutoffs. Although I would suggest you to sit for the April session and give your best in that exam since you are lagging behind by just a little difference. Solve the previous years' papers, brush up your concepts and revise thoroughly.
