I am in grade 10 and up to now I wanted to be a doctor, but I have recently changed my mind to business. But I heard the only way to be successful in business is to make it into a top business school such as Harvard, Stanford, Wharton or Ivey. THe problem I haven't exactly taken any business like courses yet so I'll start in grade 11. WHat courses are good to take to get into a top business school. Is it good to take all 3 sciences or law or economics? Thanks for any tips.
