<p>I haven't read anything on Penn's website that explicitly states anything about this. Is it just a given that all schools that use the Common App accept rec letters electronically?</p>
<p>Oh, and if my teachers were to physically send their letters, around how long before the deadline should they send their letters?</p>
<p>I’m not sure. Both of the teachers I asked last spring told me to prepare envelopes for them, so I think they prefer sending their letters via snail mail. I haven’t started school yet, but when I do, I’m going to ask them if they would mind submitting their letters electronically. I’m just uncomfortable with the idea of physically sending the letters because they can get lost or take a longer time than expected to arrive to the schools.</p>
<p>Colleges prefer electronic letters and if a teacher prefers to mail them, then it is upto you to ensure you collect the addresses where a school will accept paper letters.</p>
<p>It seems like Penn is trying make it hard for anyone wanting to send postal mail which means you should call and ask.</p>
