<p>I’m in the process of ordering books and I saw that I needed Psychological Science for my Intro to Psych as a natural science. On the website, it said I needed the third edition of the book. I have found the second edition for MUCH cheaper and am wondering if it’s worth the risk to buy it. I really don’t want to spend that much money, so is it okay if I get the second edition instead? Would it really make that much of a difference?</p>
<p>probably best just to e-mail the prof and ask him.</p>
