<p>So for my physics 2 class I'm taking next quarter (Benjamin Grinstein is the professor) I'm required to pay for this online service called WebAssign that he uses. Along with this purchase ($25) comes an "e-book" which is an online version of the textbook we need, but we can also purchase an actual book for $25 extra. For you students who have taken this class, is it better to get an actual book, or can you do well in the class with just the e-book thing?</p>
<p>Thanks in advance!</p>
