Credit for AP U.S. History

<p>Alright so I got a 3 on the AP U.S. History exam. I want to apply to most of the UC's and USC, and I read on their websites that a score of 3 or higher would satisfy the whole history requirement completely. Is this true? I don't want to find out that I actually needed a 4 instead of a 3, because then taking the exam would have been useless.</p>
