Hey everyone, just a quick question. I'm going to self-study psychology this year and want to use a textbook, even though I know a lot of people say they just use a study guide like barron's. For my textbook, I want to use a David Myers book as they seem to be the best. I don't want to spend too much money, though, so do you think it would be okay if I used a used an 8th edition from 2006 instead of the new 9th edition of Psychology from 2010? I'll still use Barron's as a side guide, too. Thanks!
