Sir, I am alloted Electrical and Computer Engineering in Amrita ,Coimbatore. is it worth joining?

Amrita, Coimbatore is quite a good college. But the fees is very high, just like other colleges of same category. The placements are quite average (4-6lpa), in almost all branches including electrical.
I dont know your rank, but it's highly advised to use a college predictor to know about your best chances.
