<p>Good evening! </p>
<p>Okay, as you know... credit card payments are processed slowly by the Common App. I do not want to risk this method, since I am close to the deadlines (yeah I know...procrastination xD). However, I noticed that it is possible to pay by "Mail Check". If I mail my checks and postmark them by tomorrow, will it be too late? I know some schools accept postmark deadlines when application materials are mailed.</p>
<p>Thank you very much! </p>
<p>(I am applying to Harvard, UPenn, and Yale)</p>
