@Angus Avagadro , you are quite off-base here. And come off uninformed. Almost as if you don't actually understand what your own Dean has told you. Sorry to be blunt. I've seen you post many times regarding these sorts of issues, and you simply seem out of touch.
As
@sab3156 mentioned, a course failure (even with remediation) will more than likely hurt the chances of applicants when applying to 1) competitive specialties or 2) top programs within all specialties. Most DO students would not be considered at these programs anyway.
However, a single course failure in the first semester of medical school (as long as it is passed during remediation) is not going to really hurt the chances for obtaining a residency for most students if he/she passes all of their subsequent courses, does well on Level 1/Step 1, does well in clinical rotations.
