Hey Kishore.

See right now telling u which college u will get is not possible as u have been provided with the percentile score in ur shift and that too in ur slot only. With this percentile u might be getting some of the average NITs for pursuing ur btech career. Wait until the concerned authority NTA announces the final result of the JEE MAINS. U can calculate the marks by simple formula.

Marks : (100- your percentile)*876649/100

Ask if any query. Good luck
