<p>If you apply as a freshman, I think you’ll have a great chance to be admitted.</p>
<p>Swarthmore is quite generous with AP credits, but can be very stingy with transfer credit, even when it comes from a well known university. It is basically up to the department head in each dept you took classes from, and they generally don’t like to give credit for classes taken elsewhere, though you might get a placement in higher level classes.</p>
<p>The advice to just take AP exams is a good one. AP credit is very straight forward, and will allow you to graduate early if you wish.</p>
<p>Good luck!</p>
