<p>AP Psychology - Barrons definitely</p>
<p>AP Physics - the difficulty depends on whether you are taking B or C. Either way, you can use Princeton Review or barrons.</p>
<p>AP - Statistics - Barrons.</p>
<p>I think the Barrons should be enough for you. Physics may be a little harder if you don’t have a good science background, but it is self studyable if you put some time into it. Psych and Stats are major easy.</p>
