<p>ok...dumb question...but are we supposed to buy books before class starts or wait until after. AND are chem clickers reusable (can i buy a used one??) thanks!</p>
<p>On the first day of class, you'll be given a class syllabus with the required materials for the class. If you know beforehand what books are needed (you can ask around from people who had the same professor before), you can buy books cheaper online through amazon and such. Watch out though, because the edition of certain textbooks changes frequently (such as Math 1A), so it wouldn't hurt to wait until school starts to find out what you need.</p>
<p>To find which textbooks you need, look up your classes on the Cal bookstore website.</p>
