I’m interested in finance or chem as a career but I’m not sure what classes are compatible and show my interest. Thoughts?
If you are a high school student, then completing a well rounded high school base curriculum like that described in http://talk.collegeconfidential.com/college-admissions/1995563-faq-high-school-college-prep-base-curriculum.html should be good preparation for college study in chemistry, finance, or other subjects.
For chemistry, the most relevant courses are chemistry, physics, and math (and biology if you are interested in biochemistry). For finance, the most relevant courses are math, economics, statistics, and psychology.
Chemistry may not have the best major-specific job and career prospects.
