<p>...with registering on the Princeton Application Tracking System?</p>
<p>i’m not sure when you applied but you have to wait 24 hours after submitting app. i was going crazy after i got the notification email and freaking out… then i saw the 24 note. if not, i’d probably call admissions next week if you can’t figure out what the problem is.</p>
<p>I wasn’t able to log in until about 12 hours after I received email confirmation from Princeton that they received my application. </p>
<p>So I’d say wait about two or three days after you submit your application.</p>
