I have got 81 percentile in physic ,59 percentile in math and 9 percentile in chemistry and the total percentile I got is 46 .what is my air

JEE Main 2019 is being conducted twice by NTA for the first time and rank will be based on NTA percentile score which will be released in the month of April. It would be tough to provide you the exact information about the qualifying marks or rank but a score more than 85 scored by the candidates as a General category might be eligible for JEE Advance.

Based on this score your probable rank will be 546,989 - 611,989, The chances are very less to qualify the exam. I would suggest you to appear for JEE Main April session again.

NOTE : Rank Predicted is on the basis of the expected total number of students i.e. 1152650 appearing in the JEE Mains April Session.

Good Luck!
