So I want to major in either Biology or Chemistry with a co-major in global health, or global health and co-major child/maternal health. For colleges to see that I am really interested in those majors should I take AP chem junior year and Ap bio senior year. or Ap calc ab junior and bc senior. Mind you that AP calc will mess up my dual enrollment courses and I really like how they are going. I also plan on taking Gen Bio 1&2 junior year and Gen Chem 1&2 senior year at my community college. I thought taking a lot of science base courses because i want to major in the sciences would make colleges see you as determined.
