Unless they change it, at my school there is a vote by the students. But it's only on the top % (the number of which I don't know). And it only really matters for people who are borderline. From what I understand. Like if you're #1, the voting doesn't matter, and you're basically already in. But if you're on the line or even a little below, but you get a crapload of votes, then you might get in.
But this is according to some 4th year students, as the faculty/staff has not addresses AOA at all so far in the first 2 years. And our school does not rank us. But they do put us in percentage blocks or something.
Bottome line: It's ******ed here.
