Given the complete and utter lack of a shit he's given about academics up to this point, it's no surprise that colleges are a little reluctant to take him. What's more of a surprise is that they seem rather less bribeable than, say, his school district, or the police, or the neighbors, or...
So the only place they could find that could be bribed, begged or blackmailed into taking him is this somewhat obscure place that may or may not primarily graduate future mob bosses. And is somewhat geographically inconvenient, which is why he is currently on a bus. The fact that the bus is otherwise completely empty aside from the driver, whose hat shadows his eyes in a remarkably creepy way, is less explicable.
