I feel as if PTCAS is using references and letters of recommendation interchangeably. I waived my rights of access to my references so I didn't get any specifics, but I was told from one reference that they were asked questions about my character, which is what a letter of recommendation would address. But are the references and the LOR separate? Is there a link to upload a LOR? I don't know what the email from PTCAS looks like so I feel blind when talking to my references about that section of the application.
