Hello Shanika,If you want to pursue engineering at reputed college then definitely you need to prepare for JEE Main again, since with 82 percentile your rank is beyond 2 lac. So, you don't have much chance of getting admission in CSE in good colleges. So, give another chance to JEE Main and hope you will get above 98-99 percentile in JEE Main. All the best.
