Chandigarh University (CU)

BBA is Bachelors of business administration and B.Sc is Bachelors in science. Both of them are two different fields. It depends upon your area of interest, whether you are interested in business or science. If you are confused, then do a little introspection and try to figure out your area of interest.

Yes, according to the new education policy all government and private colleges get admission through JEE score, but you can get admission through university's entrance exam.

I have never heard about BE in cloud computing. If it is, I really appreciate our education system for launching such specific programs to make perfect engineers. If it is there, you will be dealing with cloud computing technologies, networking, virtualization, automation and all of those specific to the area of cloud.
Being in computer system, you will learn full stack courses of computer science like databases, operating systems, networking, programming, data structures and many more. Anyways, those are then pre-requisite for being successful in cloud computing area.

Dear Sumedha Das,
I am sure Chandigarh University offers admission based on CAT, MAT, etc. Therefore, forget your CGA and try to do something in the entrance test.
All the best.

It is a private university, which offers you a good array of education environment and good ambience for study and library and hostel facility for their students. It is a good university for MBA because it contains of experience faculty member, which spread the blossom of knowledge in the university.
