Architecture exams in Mumbai are tough. You need to get a minimum of 55-60% in 12th to get through. Then there is a test provided by the professors to test the knowledge of architecture that you're going to pursue here. Finally, a small interview round is conducted to test how confident you are in the field that you're about to take. Once all these is cleared you can get admission in Amity University Mumbai.
