DTU - Delhi Technological University

VIPS is affiliated to IP and DTU is a university. Both are state universities. So there is not much difference. I will prefer DTU. But you can take into consideration factors like specializations, fees, nearness. Etc.

DTU name is big but among BBA courses IP is considered also as a top notch. But, DU BBA is best so don't go for A & B go for C I. e. DU.

Not core CSE branch, but you can get software engineering in spot round.

Mechanical engineering from a reputed college is much better than any non reputed college's CSE, until and unless you are a code freak who is very confident that you will take your skills to that level where college doesn't matter. Then only you have to go for a Computer engineering from dy Patil College of engineering.

I don't think so , as you are a outside delhi student with no category would be a problem.But there's a chance

Yes, you can get a seat in DTU.

If you are a general category student you will have a little chance of securing a seat in DTU/NSIT lower branches.

You might have a chance to get ECE in NSUT new campuses I. e. East and West campus.

In my opinion, you should choose firstly NIT Jamshedpur then DTU Then BIT then another one for the CSE branch.
