<p>I've already sent my Stanford application, and I wanted to add that I've taken some math classes in my free time but didn't get a chance to put it on the app (I didn't want to put it in the extenuating circumstances section). Should I email the admissions director to let him/her know? Or should I talk to someone else?</p>
<p>Don't email. You won't get a response for weeks. Call the admission office (after break, of course) and tell them directly. They'll probably let you do the change online if you applied online.</p>
<p>I had tried adding information via email after my app was submitted, so I guess email works.</p>
