This is a call for help! I've been recruited into the big leagues!

And by big leagues I mean, a charity trivia tournament. These people are extremely competitive (of the "crush your enemies, see them driven before you, and hear the lamentation of their women" variety) so it's a great honour to be asked. I'm terrified of not living up to expectations (I only know two of my teammates and I don't want a disappointing performance to embarrass them in front of the others) . So O-deckers, you are my only hope. I need websites, podcasts and other suggestions on how to boost my trivia knowledge (besides my current plan of re-watching every episode of QI). I'm looking to cover (generally) biology, astronomy, history and literature. Brain teasers and logic puzzles could also be included. My biology degree and bibliophilia should help, but I'm looking for any resources to help me crush the competition.
