I have one of my friends studying B.Tech from Amity University Noida. Here are the following points which will help you in making a decision.

• Faculty: Amity University faculty is not good. The university does not have skilled and professional professors. Their teaching method is also not up to the mark. It lacks in providing practical knowledge to students.
• Placement: The Bio department of Amity University is not good and at least 90% of its students are still unplaced.
• Infrastructure: Amity University has a great infrastructure facility. 
• Attendance: The Amity University has 75% mandatory attendance for all students and departments.

Therefore, Amity University may not be a good option for taking admission. As everything shown in brochures and pamphlets might be misleading. The ranking of the college and universities have nothing to do with its education and placement. So, before taking admission do your own research and find a suitable college according to that.
