It is quite impossible to get top branches like CSE, IT, AIML in any colleges of IPU because your rank is not upto mark but in affiliated colleges for the candidates,  you can get admission for branches like ECE, EEE, Mechanical in less popular colleges such as GTBIT, DTC for sure and there is a very less chance to get seat in mid-tier colleges like BPIT, Akhilesh das if you go with low branches if try till the spot round, so i would suggest you to fill your choices accordingly and try to prefer a college which is near your home.
