im really confused about what book to get to help me study for the pcats. apparently all of them have mistakes in them so i really want to get the best one. i see people saying collins is the best but thats a lot of money and i just want a book like kaplan or barrons for example. what about pcat destroyer?(its advertised here so is it good).. i was originally planning on getting barrons and cliffs practice tests but as i kept researching i saw more people saying bad things about barrons. so basically what did you use? what do you recommend? help!!
