Yes, you can get SRM Chennai easily.

SRM main campus for CSE is better to manipal in every aspect I would say. You have better opportunities from them better placement better college better campus life.

No, cut-off is there for BBA, you will get admission in BBA easily.

You can join SRM for hotel management they have really good placement record. The course they offer and the facilities are ample for you to learn and best is it is in your budget and my honest opinion you should join SRM. The location is also a big advantage for SRM it is in outer skirts of Chennai but very well connected to Chennai with local trains and buses.

SRM provides top placements, top faculty members as well as good infrastructure but the university fee is very high. If you choose economically, then DTU will be the best. DTU also provides good placements.
