SAT II Subject Tests, AP tests, or both?

<p>Some colleges prefer that you take 2-3 SAT II Subject Tests, but I had a quesrtion regarding subjects that overlap between SAT II Subject tests and AP tests. If you take the SAT Subject Test in World History and the AP World History exam which one would colleges count? Also, if you were to get a "3" on one AP test and 4s or better on the following eight tests would getting a "3" disqualify you from becoming an AP National Scholar?</p>
