I am currently a Chemistry junior in UCB (Asian, international, female). I chose Chemistry as freshman basically because I wanted a major that combined math and science (especially health field). Then I had a summer intern in lab this summer and found I didn't like the experience. I never thought I could pursue health field in stats major until I found biostats. Since I have other major requirements, I can probably add only 5 extra math/stats/cs courses in my four semesters (maybe more if I don't do research during summer). Also, most of my upper division chemistry courses are analytical (stats-related) and physical chemistry (calculus, linear algebra and differential equation as prerequisite). Courses I've taken in lower division: Calculus 1, 2, 3 Linear Algebra Differential Equation Course currently taking: Probability Courses considering: Concepts in Computing with Data (with R) Concepts of Statistics (with R, the course above as prerequisite) Real analysis 1, 2 Numerical analysis 1,2 upper division linear algebra Programming (Python, C, Java, etc.) Please mention other recommended courses if needed. Also, should I consider MS only since relatively I do not have a strong math background? Thank you in advance for the advice.
