Hi,

The admissions does not always go by the cutoff list. A college has a limited number of seats and if the seats get filled faster then even if a candidate qualifies for the college according to the cutoff list, he/she won't be able to get the college. So this must have happened in your case, that even if you were eligible for Acropolis, but the seat got completed so they shifted you to another college in your preference order.

I hope I was able to clear query

Thank You
