Hey Kaif,

Galgotia University is Currently Most popular private University in Uttar Pradesh Currently. But the best is Amity University yes it's expensive but You can Check NIRF ranking to know why it is. Galgotia University is expensive not as much as Amity but still more then others and the lifestyle in GU is Too. 

Regarding Curriculum And Placements it's Quite good. With Quite Good Companies Visiting campus every year. Overall If You are serious for education it's a good university.

Best of Luck
