Should I take admission in some college of GGSIPU or should a take a second drop tear to give JEE MAINS for the third time?

It's completely your call that if you want to drop another year for mains or to take any other college but I would suggest you to rather take a college GGSIPU you got a decent rank in it hence you'll manage to get some college as jee mains is one of the most desired engineering entrance exams as it is a matter of some hours that decides your fate so don't waste another year for it and so for some other college but as I told you it's your call in the end .
Good luck!!
