Cross country, AP physics, or drama club?

In my opinion, AP physics would be the way to go. Assuming you can handle it, it will save you money for college and possibly even help you get in, if you do well. Depending on the situation I might try all three, but you know your limits better than I. Cross-country is a lot of fun and it gets you in great shape, I am a runner, but I think I would go with physics in the long run.
