<p>I have decent SAT Verbal at 670, terrible SAT II writing score at 600, but I scored a 4 on my AP lang exam.</p>
<p>I think it might have been the pressure for the SAT II...because I scored even lower on my second try.</p>
<p>Never really been much of a writer though....</p>
<p>All things being equal, there should be correlation. However, as you have pointed out, as soon as you factor in stress, you get odd results. Your AP score is very good. Don't worry about the SAT II Writing. Last year, there was a parent's thread that just flamed the whole test format.</p>
<p>I agree that there should be some correlation, but the AP test emphasizes much different skills than do the verbal and writing tests, which themselves cover material that is unique to the specific test.</p>
<p>In contrast, I think that something like AP US History and SAT II US History will have a very high correlation because they require very similar knowledge.</p>
