<p>My friend is applying to Princeton and is filling out the commonapp version/supplement. However, she gave her teachers the rec forms from the Princeton-specific app (the one from their website). Is this a problem?</p>
<p>No, it is not.
I'm curious why you didn't use the entire Princeton App though?
Because you were applying to many other schools using the common and didn't want to take the time/effort to fill out their app and write their 2 specific rather than just using the common and sending off one of theirs? They will notice that you expect your teachers to put in the extra effort but did not yourself...just saying.</p>
<p>Well I think there's a reason they accept the common app...and they don't care which one you send in, they say that on their website.</p>
