<p>Does anybody know how this works?
I see it for Math 19B. From Baytree bookstore you can buy 1 or 3 quarters with a big break for buying the 3 quarters. But if you buy 3 quarters:</p>
<p>1) Do the quarters have to be contiguous?
2) Do they have to be used for a series (19A,B...)?
3) If the answers to the two questions above are both "no", is webassign used by a lot of professors, i.e. is it likely that all three purchased quarters will be used within any time limits that apply?</p>
<p>I'm cheap. What can I say?</p>
