Hey Mohit ,
Greetings!

I would like to tell you that they have one branch in Noida , and one branch in Greater Noida.
I would suggest you to opt for Amity University , Noida if you have to choose between these 2 as Greater Noida branch has just opened an year back but Noida branch is one of the oldest one.

Hope this will help . Good Luck ! You can reply to this comment if you have any further queries , I will be happy to help .
