<p>I am a freshman taking World History on June 2nd. I took the AP exam today. Will I be okay by using my Princeton Review for the AP course? Or should I buy the guide by Princeton that prepares for World History and US History SAT IIs specifically? The only reason I consider this is because I know I will take US History SAT II next year and was wondering if this would be a decent investment.</p>
<p>And when are scores received?</p>
