Your letters should focus specifically on your qualifications for the specific Penn Engieering program you are applying for, so we encourage you not to reuse letters from a different program. If you’re reapplying, your recommenders may resubmit the previously written letters with your new application. If you started an application in a previous term but never submitted and are now applying to the current term, your recommenders will have to resubmit their letter or you may choose new recommenders.
