<p>I don’t think there’s a real “minimum” for AP credits. They want to see that you take a challenging course load (from what I’ve heard), but it’s more about using your school’s resources than taking a certain number of AP courses. For instance, at my school, there were only two AP courses available for me to take before my senior year–now there is only one, as the other got canceled. I took both of them and another test on my own–it’s not 6 credits, but I used the resources at my high school as best I could.</p>
