I hav secured 94 in NATA,143 in paper2 JEE & hav 60% in +2.I was eligible for choice filling in JEE's CSAB but didn't got even in spot round

Now there are very few colleges left with admissions still open. even gujrat's ACPC wasn't a good help. Should i drop this year & reappear for boards & NATA again to improve my scores? I want obviously renowned and good colleges.
