If You Know You'll Get an MBA it could make sense to get a degree in the sciences or humanities first says Geoff Gloeckler. Even if you missed out on a liberal arts education at the undergraduate level you can still take some humanities and economics at the graduate level as well. Some extra months taking extra courses could also be considered good continuing education. It is never too late to catch up. You may never want to forsake attending the self-taught university in your very own study. However, getting tested proves competency.
