ucla extension offers enough classes to meet almost all requirements. it's not a formal post-bac program as such (so there aren't any 'stats' about how many get into med/dent/pharm school); but I did all my stuff here & got into some d schools, as did a friend of mine.
but then again, we're old, non-traditional applicants
but then again again, before i picked ucla, I called a few schools & they said they had ppl who had come from here; so it's not a bad option
(plus, its much more affordable at only $400-500 per class; USC is $4000 per class from what i hear) Scripps has some insanely good stats from what I remember - like over 90% of ppl who get in & finish their post bac get into a school.
well, good luck! just wanted to throw out the ookla alternative
