<p>TO replaces the USC core GE requirements; it’s basically another form of GEs. </p>
<p>As for the elective credits, I believe you’ll receive credit for 8 units for Calc AB and BC, and 12 units for APUSH, World History and Euro. At the end of the day, your AP credits just go toward your registration time for classes and nothing more. (The more credits you have, the earlier your registration time.)</p>
