I'm thinking about buying Kaplan PCAT 2006-2007 book but have read that it has numerous errors. However, even with the errors, a lot of people recommend it. Does anyone know if there is someplace online, kaplan.com or otherwise, where you can find out where the mistakes are? I believe I read that one mistake was in the photosynthesis section. If there is no online page for the mistakes, I would like to see if any of you would like to start a thread listing mistakes you've come across so we'll all be aware of issues that we may encounter.
