SRM Institute of Science and Technology, Kattankulathur

There is no exact cut-off as they want to fool you and want to make you feel inferior they will put you on waiting list they will tell you that the cut-off is going to be high and they say that they want high-quality students but when you take admission in any branch, you will see that there are more average students who were not even eligible for engineering (on intelligence level) in your class.
So, they don't have any cut-off if you got money.

To secure a seat you need to have a rank below 5000. Further, the ranks are admitted according to the financial attraction of the course and the time of admission.

Yes, I would say there are chances of you getting admission in the main campus under A category. If not we always have the category as an option. Just keep your fingers crossed and attend the counselling. Tuition fee:
A category: 1,80,000
B category: 2,50,000.

College timings for B.Com students will be 8.50 AM to 3 PM from Monday to Friday.

You need not write any entrance exam in order to get admission in SRM Law School, Chennai. Since it is a new law school it accepts almost everyone with minimum qualifications prescribed by bar council of India.

There is no such special requirements by SRM Law School and you will get admission even if you have only 50%.

I can see that your first preference is branch means you want to do B.Tech in CSE then definitely you should go with SRM. You will get more exposure there.

All three are good. If you want a college near you, then go for Jaypee. If you want exposure from east and central India, then go for KIIT, if you want wider exposure then go for SRM.
