there's a few videos that might be worth checking out if you're really rusty. I got some from the teaching company. I forget the name of them, and I'm not at home to check it out, but if you google the teaching company you'll find them. They are classroom style lectures. I picked up the gen chem and gen bio sets. Also, I picked up a few videos by the standard deviants. Very cheesy stuff, but they might help brush off some cobwebs. Good luck!
