<p>I am having a little trouble in my AP Calc AB and AP Biology classes this year. So, would it be good for me to by the AP books now and use them as I study for tests?</p>
<p>Thanks</p>
<p>I would simply solve as many problems (either from your textbook or the MC Collection available on the CB website) as possible for AP Calc rather than buy a prep book.</p>
<p>In general, it is a good idea to use AP prep books to help you learn the material throughout the year - and it will also serve as a good review book for you in May. See the Consolidated List for the recommended AP Bio book suggestion.</p>
