Recommendation letters

<p>Should I be using
a) the Common App generic teacher recommendation form?
b) forms 3A and 3B from the Penn website?</p>

<p>or are both acceptable?</p>

<p>and I read somewhere that having them do it online is an option, but I can’t find a URL.</p>

<p>Thanks.</p>

<p>Depends if you're using common app or penn app, use the corresponding teacher rec sheet</p>
