Hey, So I'd like to do the International Physics Olympiad (IPhO) next year, and I was wondering what any of you wonderful physicists would suggest as adequate preparation, particularly those who have done IPhO before. I live in Ontario so I've looked at the University of Toronto Prep. Questions, and I have Fundamentals 7th Ed. (Halliday/Resnick/Walker), and that book looks quite good (it's our grade 12 text), although it's probably not enough. It's not as simple as buying a first or second year university book I don't think, since I don't have that level of math knowledge/ability and IPhO does not require any undergraduate math. So, any resources or textbooks would be of great help. Thanks a lot (and good luck to whoever else wants to do IPhO, should be just as good as IChO).
