You should register for CSAB and then you should fill your college priorities according to your preferences and be sure to include all the colleges in it. You will get into one college on that list, if your rank is good enough. Your rank will be very far, around 200000. You should consider getting into a private college, as you have asked me which college will be good for you. Or you should consider other universities such as GGSIPU or UPTU if you have given their entrance exams.
