I agree with WOWM. There is little explanation can be done in the med school application. There are 7-8000 applicants applying to any single med school every year, so the competition is fierce, the adcomms will compare your stats with all the others and if they have to pick 100 out of 7000 which would they prefer? A student take P/F on chemistry or an A in one sitting? While not every single course will determine your acceptance, that one score alone is one strike to your application.
I think if you do well in Davis you will have a better chance to get into a med school, rather than make a lateral move to a smaller school, some thing like Azusa or Mills for example , unless you can upgrade your school to like Middlebury or Mudd. You need to review the success rate from the target school before jump ships. OTOH, if you are failing(to be competitive for med school) in Davis, this discussion is basically academic.
