JEE Main

Hello Pankaj, Irrespective of whatever you score in JEE Mains, NTA will allot you a percentile and also ranking as per your category. Normally speaking approximately top 300000 students are allowed appear for JEE Advanced but there is nothing like pass or failed. NTA calls it by the name of cutoff. You will come to know slowly and slowly as NTA announces the results in newspapers after completion of both the cycles of JEE Mains. Best wishes to you.

Hello Impana, There are about 40,000 seats approximately in different NIT's. Your percentile is about 71. But rather than only percentile ranking which will be released by NTA in OBC category will be more helpful. There is possibility of getting admission. However to help you, I am attaching one link that will predict college for you based on your percentile. https://www.shiksha.com/engineering/jee-main-college-predictor
Best wishes to you.

It depends on your Mains rank and sometimes on your board percentage also.

Yours expected JEE Main AIR is about 198370. The admission in IIITs is seems difficult at this percentile. However you can be hopeful for the following IIITs during special rounds of counselling.
1. IIIT Dharwad
2. IIIT Kalyani
