<p>I'm taking two summer classes, and Courserank and the Cal Bookstore Online have already told me what book I need. Am I supposed to buy it beforehand and bring it to class on the first day? I'm just worried that I'll buy it and on the off chance it turns out we need a different book or something.</p>
<p>Also what's your guys's opinion on renting textbooks versus buying new? Renting on Chegg specifically. Does anyone have any experience on this? How are the conditions of the books?</p>
<p>Thanks in advance!</p>
