Today was Klaus' first day at college--basic chemistry class at our local technical college. Turns out he's the only boy in the class. On the other hand, the teacher already knows him by name. ;-)
He also doesn't think anyone knows he's fifteen, which he feels both good and bad about. I suggested he could wear a sign around his neck that said, "Baby". For some reason that didn't appeal to him.
If it were a traditional high school class, i.e. 1 hour a day for 36 weeks, I would be concerned whether he was getting enough challenge--he was the only one in the class who knew air had matter--but since the class is compressed into 16 weeks, it will have a quicker pace and less repetition. He doesn't actually know everything there is to know about chemistry (despite what he says) and this class will get to the stuff he doesn't know much more quickly. Hallelujah!
