<p>Hi, I'm a newly declared Psych major and I'm taking my first upper division psych courses this fall (101, 104, and 180). I was wondering if it is usually necessary to buy the study guides that go along with the text book, or are they a big waste of money.</p>
<p>Also, I've heard mixed reviews about 180. Does anyone have opinions on it? I'm taking it with Sweet.</p>
<p>Thanks for your help :)</p>
