Well, to keep the show going for as long as it can, they're going to have to make the actors look young enough to retain the credibility of them being eleventh graders. Ergo, make-up. Although it's not really necessary (after all, they're only two ears or so older than their characters), that's just the way Hollywood words sometimes.
