<p>So after reading the list of good books to have to review for AP exams, since I'm taking Calculus BC next year, I figured I would get a head start and read a few chapters over the summer. However, when I try to find the book online in places such as half.com and Amazon, the book is almost $200? For some reason the 2000 edition is less than $10, but the 2002 edition jumps to $200... can anybody explain this?</p>
<p>I prefer to get a more recent edition like 2007 because, I know that prep books rarely change with each edition, but I figured a 2000 edition will not be quite as up to date because its been 10 year since that edition was published.</p>
<p>So therefore, anybody can tell me where they bought their book or good places to buy them at a reasonable price?</p>
