I have the EK 1001 questions for chem, physics, and o.chem and I even have the 101 verbal passages, but I don't have anything for biology (they're sold out ). So what are you doing to test your knowledge about biology besides the practice MCAT's?
the biology that they test you will not be recalling general bio concepts. But they will passage based questions, just like verbal. Even if you are pundit in bio, you must be extremely good in figuring out the bio passages. I would suggest you look at the AAMC 6R bio section, for a true feel of mcat bio.
