You should definitely use a book I found called "Random stats questions and obscure minutia you learned as a first year medical student." If I would have read that book, I would have maybe been able to answer the many questions on the students t test, carcinoid syndrome, and starlings law of oncotic forces in patients with liver failure. 😎
Sorry for the smart ass answer but it really seems like the key to this exam is not how much you study but how well you learn how to answer their tricky questions. I think I am going to be taking a review course in the future.
