sir my ews rank is 45k but my percentile is 69 .
so can i get any college through jossa??

Shadab This year the ews cutoff was nearly 70 percentile, and your percentile score is around 69. So there is a 30% chance that you will get in jossa all rounds counseling (as you have not cleared the cutoff) but if you don't get then you may try your luck in CSAB round as the chances are better in CSAB for you, but always remember getting a seat via CSAB is all about luck. According to me you must prepare once again and with a good confidence and you'll surely crack the eaxm next time.
