I'm also going to give very general advice (which you have not asked for), without any knowledge of your personal circumstances, but if you are at the beginning of the pre-med journey as a post-bacc student in Los Angeles I would suggest thinking about the possibility of going elsewhere to do it. Getting into one of the UC medical schools is insanely competitive. Typically, your in-state schools are your safer bets when you apply to medical school. When I applied (twice), I had 4 interview invites each time, but only got one secondary invitation from one UC medical school. It's just a different ballgame in California. If you could find a way to go to, say Texas, you might be doing your future applicant self a big favor, as well as future doctor self because of the financial savings (look it up on MSAR). Although this seems radical, this is one thing that I wish I had thought more about doing.
