<p>Biology- Sparknotes and PR (Which Book is more helpful I have both- I'll try and get through both)</p>
<p>US History- Sparknotes (the Deluxe Internet Edition =p)</p>
<p>Math2c- Barrons, Kaplan, and PR 1&2 combo (which one is best here? I looked over Barron's and found it to be very in depth- the spark notes one looks good any suggestions?)</p>
<p>From my experience I tend to trust Sparknotes, something about their prep books makes me feel prepared. (Barrons is the same way). Overall, I tend to use the AP books to prep except for Math I and Math II. But to answer your question.
Biology: Sparknotes (Use Cliffs AP if you have it)
US History: Well you only bought one book
Math II: Barrons definitely.</p>
<p>haha, I thought I was the only one who used multiple books per test... I'm working with both Sparknotes and Barrons for the math IIC. But I'm not really sure which one I like better, because I haven't yet taken the actual test, so I don't know how they both compare to the real thing.</p>
<p>One thing is, though, in both of the books, my scores are not very consistent. In Sparknotes I get anything from 710 to 800, and in Barrons I've gotten from 690 to 780...</p>
