If you're applying to go to a particular college in the fall, the first week of April is usually the time to find out whether or not you've been accepted, and then you have to notify the school by the first part of May if you accept the invitation. Every school works differently, but that seems to be the general trend.
SFA is taking applications for the fall, and they've posted info on how to apply on their website.
There is one school in the US that gets more than 38,000 applications every year, and accepts only 2200 new students. Any guess? It's an Ivy League school.
