I studied business in college. Our finance courses basically taught us two things: how to estimate the value of assets (including machinery, businesses, real estate, options, or whatever else you might want to buy), and how the modern international financial system works. That means we spent most of our time learning and practicing valuation calculations of various types, or reading case studies or articles about financial regulations and financial markets. We learned about the CAPM and the basics of portfolio theory. We learned about what options are and how to value them. We learned how investment banks make money and some of the terms used in the field.
