Am i eligible for nit, i scored 44 percentile and my category is ST
JEE Main is being conducted twice by NTA for the first time so it would be tough to provide you the exact information about the qualify marks or admission eligibility.
Based on this score your probable rank will be 613,446 - 678,446 and your probable category rank range will be 19535 - 21135. You may not be eligible for JEE Advance & NIT admission also.
NOTE : The 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!
