With a rank of 741783 in the General category in JEE Main, admission to NITs, IIITs, or government engineering colleges through JoSAA/CSAB is not possible. But you can possibly get admission in private universities such as LPU, SRM, Amity, or through state-level counselling in certain aided or private colleges. Look at the backup alternatives such as diploma-to-degree (lateral entry), improvement year, or application to universities with their own entrances. If you happen to be part of a reserved class, possibilities may marginally increase. Investigate state counselling or direct admission in private colleges on availability.
