Computer Science and Engineering Ranking

No, for CSE, this rank will not be sufficient. Moreover, you may get a low ranking college with one of the non technical branches. Some of the suggestions be NIT Pondicherry, Silchar, Manipur. Since, these are only suggestion and personally I feel not worth going into any of these for distance education. Also, private colleges or drop are two options left with you.

It depends on two things first it depends on your living state as the cutoff of IPU is divided into 2 parts Delhite students and non Delhite. Usually the Delhite students get higher preference as there is a 85% quota for Delhi students reserved in IPU. Secondly it depends on the category you belongs to if you are a general category student then its very difficult to get in IPU. But I will suggest you to attend the spot counseling as there is a huge chance of selection through spot counseling.
