What classes should I take to get finance jobs?

Whatever classes you take, in order to be competitive for top Wall Street jobs you should aim to keep your GPA over 3.5. After that consideration, you should try to take a mix of business, economics, accounting and finance courses to show a strong interest in relevant concepts to Wall Street careers. Once you have a nice base of those relevant classes, you should take whatever interests you most in order to highlight that you are a well rounded candidate.
