Should I just go up to him? I have him in two classes. What would I say?

Stop caring what the outcome will be. That's what worked for me, but then again, I always have that nonchalant style, so it may be a bit more difficult for you.

Go for it! I mean, its your last chance! Take it! Don't think about you being shy, just come up to him and say 'hey, how is it going?/how was class?' Then ask about his interests (his favorite sport, what he would like to do when he is older, what uni, any siblings?, favorite hobbies? does he have a part time job) Anything really. Just put yourself out there, that's what he is waiting for. He just needs a perfect green light before doing anything.
Hope that helps and good luck!
