<p>Any suggestions for how a student could find help preparing for the AB exam if his teacher is mediocre and has a poor AP exam track record? I didn't realize my son's math courses had been so poor until he went to take the SAT math II and didn't know a third of the information. I don't want him to have a repeat of that situation when it's time for the AP exam next May. The lowest grade he's gotten on a math course is a B+ one semester. He'll be taking both statistics and AB calculus as a sophomore next year.</p>
<p>get a good prep book, such as Barrons. I used that.</p>
