Let’s face it: getting into the MBA program of your choice isn’t always easy. This may be especially true for younger people with less work experience, or would-be applicants with liberal arts or science backgrounds – valid pursuits, but not directly linked in an admissions director’s mind to making someone B-school ready. And once you’re in, will you be able to keep up with the math wizards sitting next to you in class? The best way to ensure you hit the ground running and don’t stumble your first year is to take classes that will help boost your skills and prepare you for the rigors of your first year as a business school student.
