Are you talking about Amity University?

If it is what is in the link, then it is not fake. You will be eligible for all graduate based exams.

Possibly, yes. Contact your college's office and tell them that you want to shift college and tell a genuine and valid reason for the transfer. They may be able to transfer you in same course if the seats are available there.

No, there is no branch of this university in Patna.

I think you should do CS IT from iiit Gwalior. But it also depends upon your convenience and interest. You can get insight of both and then take decision. Best of luck.

NLU Ranchi is for better as compared to NLU Patna. You should choose NLU Ranchi, but it also depends on your budget, accommodation and rest other factors. Good luck.

Career Launcher is a good brand of teaching and preparing quality competitors for the MBA entrance examinations. You can visit the center and appear for demo exam. It has a good study material as well as teaching staff.

You haven't quoted your 12th marks without which one can't suggest you suitable colleges. Then also the best colleges for commerce are:
1. College of Commerce, Rajendra Nagar
2. Vanijya Mahavidyalay, PU Campus
3. A. N. College, Boring Road
4. B. N. College, Ashok Rajpath
Apart from that, many tier-2 colleges are there. For forms and admission procedure visit these colleges and ask from their reception or admission counter.

Hi,
St. Xaviers College of Management and Technology is one of the good college. Academics and infrastructure are good here. And, placement record is also better than many other colleges. Regards.
