Ravenshaw University

Yes, there will be some aptitude and reasoning questions there. So prepare well.
Good luck!

Chances are less for BBA after Diploma, but I will suggest you that go for B.Tech in civil engineering, because as compared to BBA, Civil is much better because after B.Tech in civil engineering, the job prospects are more as well, as through your B.Tech degree, you can get PWD license, and by that you can set your future. So, choice is yours.

B.Sc. ITM in Ravenshaw University is a better option because its placements are good and also, students get many opportunities to bring out their ideas.

I would suggest you B.Tech from Hitech College as an engineering degree comes with a lot of scope and opportunities than the normal science graduate degree. It will also give you a brief outlook of subjects related to management thereby serving your interest areas in later. But if you are planning to go for engineering please take up IT or CSE as specialisation.
