Hi Arjun!This is Neeraj Atluri.Congrats for scoring a good scores.Simple answer to your question is,Ask your self that repeat Jee  advance or Other colleges.Your having a good chance to join in many colleges,but if you repeat JEE Advance ,One year will be wasted,besides if you score a bad score then Its difficult for you to gain a good seat.So in my view joining in Other best colleges is the best way.
