If you want to be a pharmacist, I’d recommend biochem since there are a lot of biochem majors who go on to that field. But really, both majors will give you a good chance at becoming a pharmacist or anything else in the health field because they’re among the more broader science majors at UCLA. I don’t really think the math is that super advanced for biochem (One of the majors I’m double majoring in at UCLA is biochem). That shouldn’t be a factor. If you choose Bio, you’ll likely have to take many botany or ecology classes that aren’t on most pharm/dent/med school requirements. But both majors will give you the right # of prereq classes for those professional schools. It’s just the extra classes that aren’t prereqs that you have to be concerned with. You will need to determine what you prefer more, extra chemistry or extra ecology/botany.

Biochem would be your best bet, as you don’t use much biology in pharmacy, besides knowing what hormones come from what part of the body, and what drugs affect what type of bacteria. It’s more common to be either a chemistry or biochem major, though I do have a few friends who are majoring in biology with plans to enter pharmacy school.

Does your school offer a pre-pharmacy tract? If so, major in Pre-Pharm, and you’ll take plenty of math, science, and chemistry, and if when your two years are up and you decided to not do pharmacy, you’ll be about 2 classes away from minoring in both biology and chemistry, which can easily be turned into a biochem/chem/biology degree.

Biology, Chemistry, or Biochemistry. You needn’t figure out which one right now. Since you will have to take the appropriate courses to go to Pharmacy school, you’ll find yourself taking introductory biology, introductory chemistry, and calculus your first year anyhow (unless you placed out of any of your courses through AP/IB), regardless of what major you are pursuing. After taking more science classes, you’ll figure out which one to do. You’ll probably will want to do the major that gives you the higher grades in the science classes, since admissions into Pharmacy or Medical School programs is difficult to obtain. Just make sure you get in all the courses you need for health careers. By the way, all of those majors will enable you to enter the health professions (except maybe for nursing, since there can be a major in nursing that you’d have to do in some colleges).
