When is the b tech entrance test of amity university?

Generally, all the universities conduct their entrance exams in May- June. However, I would advise you to look for interesting and unique programs like automotive designing, mechatronics, power system engineering,geo science engineering etc. As these are core sector programs these will help you get a good job in any multinational organisation with a good designation. So, if these programs interests you then look for UPES,Dehradun as it is one of the famous universities in pan asia region.
