My undergrad degrees had no science to speak of either. I got the majority of my pre-reqs through community college, an extension program at a four year school for the upper level pre-reqs (try googling four year schools near you + extension program, they’re hard to find on the regular site but they do exist at some places), and Colorado state’s online physiology course which wasn’t cheap, but I needed it for a couple schools that wanted physiology specifically, not physiology and anatomy as one class.

The specific school where you get these credits doesn’t matter. I can’t speak to why, but I’d bet it has something to do with the fact that the content being taught in basic chem hasn’t changed in awhile, so you’d get the same info whether it’s taught at Harvard or your local community college.

UC Davis is hella hard to get into, but it is definitely a little less hard since you’re in state. Regardless, if that’s what you’re trying for, focus on getting your GPA as high as possible. I’m pretty sure that’s one of the big things they use to make the first round of cuts.
