<p>collegeshopping, I suggest that you take a look at the AP regulations, in the pamphlet that is distributed to the students. It is probably also available online. If a student wishes to take exams with conflicting schedules, then the student is entitled to take one of them during the make-up period (after the two weeks), with no extra charge.<br>
I agree with several posters that dual credit is not equivalent to having an AP score. marite commented that Harvard will not grant credit for college courses taken in high school, and I’ll add Yale to that group–but they will give credit (of some variety, anyway) based on AP exams.
A little known fact that doesn’t seem to be advertised in the AP pamphlets–there is even a late-late exam period, for students who have conflicts with both regular and late exam periods. QMP took one late-late exam, due to university exams in multi-section courses that conflicted with the regular AP schedule; then two of the AP’s had the same times in the late administration. I wouldn’t be surprised if students with a very large number of AP’s also experienced this.</p>
