I don't mind that there are several different types of pre-health SDNers on this postbac forum. I know it's listed under the pre-medical forums, but I think it fits well for a variety of pre-health students.
For the career changers, many of the pre-reqs are the same. Whether you're pre-med, pre-dent, pre-optometry, pre-vet, pre-pharm, etc., you'll still probably be taking bio I and II, chem I and II, organic I and II, and sometimes physics I and II. For those seeking enhancement of their academic credentials, there are postbac programs that work well for both (e.g., BU, UMDNJ, Colorado State).
This forum does seem to be dominated by premeds, but that should be expected considering that most of the SDN users are premed/med/postgrad students.
I've noticed that some of the pre-dent users here have picked up quite a bit of knowledge on pre-med admissions and give some good advice about pre-med stuff, even though they're pre-dent. Certainly there are some analogous aspects with dental/medical admissions, but I'm still quite impressed with how much some of these non-premeds have picked up about pre-med admissions.
