I agree that amity university is one of the indias big university. It has its branches in many cities but its just for people who can spend a lot of money on their education. Inspite of spending lots of money you wont get good quality of education.
Also this is yhe university with good marks never go. It has no good records of placrment. Only thing is it has good infrastrucure with lots of extra activities. I would not suggest good students to go in this university but yes if you have lots of money you approach to this university.
