What rank in AIEEE will lead to get admission in Amrita-Coimbatore?

I cannot tell you the exact rank cutoff as it varies on a lot of parameters and they change every year. I can tell you that a Tamil Nadu candidate has a good chance of getting a course at Coimbatore campus, if he or she has an AEEE AIR <10000 on a merit basis. However for ranks above 15000, one may have to come in through a management admit, which involves a higher cost.

There are no fixed rank it varies according to coruses
