What will be the cut off for SC candidate for jee main paper 1 (2019)
JEE Main 2019 is being conducted twice by NTA for the first time & rank will be based on NTA percentile score which will be decleaded in the month of April so the exact prediction would be difficult for the qualifying score or rank.
If you share your JEE Main percentile scored in JEE Main January session then I can help you with the qualify score or admission possibilities.
Good Luck!
