I'm currently waitlisted for Psych 130 with Harvey next Spring and I'll probably get into the class. I'm trying to look for textbooks now, but when I look online, it says that there's a regular version of the textbook and a binder version as well. I'm assuming I would only need one of those because they seem to be the same, right? Also there's a study guide for the textbooks (11th edition), it is necessary/important to get that? There's also a barchart, but it says its optional. Thanks for the information from anyone who's had Harvey for Psych 130 before.
