my son has got 2524 rank in pessat 2019 which branch of engg can he get in pes college

Hi,  at 2524 your chances are bleak of getting a good stream at PES. Almost all seats of CSE, ECE, EEE close at max of 1600 rank.  You could try for civil or biotech but then again chances are low. At 2100 you stood a better chance, but at 2524, chances are low.  Also,  if you are going to choose the field based on the college, I would recommend you to not do that. Join the course that, inspired you and you have interest in it. Otherwise four years of your life would go to waste even from a good college. If you have given kcet,  then you could also try through that. I would suggest go according to your interest and not according to the college that you could get.
