<p>So i emailed upenn about 2 weeks ago and still no response!
I asked them if I could still apply as a transfer if i only had one letter of recommendation.
Right now that is the only thing keeping me from applying. Does anyone know if 2 letters or rec are absolutely necessary?</p>
<p>Think of your competing applicants. The fact that you can only get one LoR would strike me as a huge albatross around your neck.</p>
