<p>My class is soon going to be finished with all the AB topics on the ap exam and want to start prepping for it while we learn the BC stuff. Is there a really good prep book that starts off with only AB topics and then goes into BC or do i have to buy one AB book and one BC book. I want to start preparing for the BC exam so i want to know the AB part really well since we finishing it in a few weeks.</p>
<p>Do you guys have any recommendations?</p>
