A Calif unhooked med school applicant w/o a stellar app needs to essentially assume that he will not be admitted to a Calif MD med school and look at Midwest mid/low tier med schools and others to add to the app list.
Calif just has too many high stats premeds, which is why Calif “exports” so many med students to other states. If you’re not high stats or hooked, look elsewhere (and concerns about top 30 or top 50 should be irrelevant).
