People replied suggesting AP bio or AP chem; counselor said no math or science and lack thereof may look weird as premed/bio, but… “I don’t want to change my schedule from what it is now. I spent a lot of time picking out this schedule…” I would point out that for Fall 2018, UCB and UCSD received 89k+ and 97K+ freshman applicants respectively. The competition is fierce among many qualified applicants. I’d guess those numbers and competition will only increase for Fall 2019. Also at least as far as UCSD, bio is a capped major.

So I guess you can add in say AP Bio/Chem (making sure you do well) and say that I gave it my best shot with a rigorous course selection (not that planned schedule is a walk in park), or you can stick to your guns, stand pat with planned schedule and apply. What’s the worst that can happen (eg rejections from UCB/UCSD/USC)? You’re a strong student and should easily get accepted somewhere. But FWIW I’d try to add additional strength (ie add math/science) to your app especially since you plan to explain away a bad semester due to a personal crisis.
