<p>I called up the bookstore and they told me it was mandatory. The book is only $60 so I doubt it's a problem for anyone getting a copy since there are only new ones. I think it's used to track work or something? Idk, but hoped this info helps. </p>
<p>Btw, none of the books are in yet so they can start answering questions after 3 days. And they're getting about 800 chem 6A books so don't do the reservation thing!</p>
<p>None of the versions that are found online says anything about an aris card… so I guess we have no choice but to buy them from the bookstore. :(</p>
<p>Whenever the bookstore gets them I guess, when we move in? They couldn’t answer my “Alice w/ Excel” question since they weren’t in stock yet though. I don’t need MS Excel if that’s what that is, because I already have it, bought it from this awesome store called “The Pirate Bay”</p>
<p>It’s the exact same version as the required one (I think), only without the questionnaire. Too bad I don’t have the emails of the other Math 20C professors, or else I’d ask them too.</p>
