GMAT = Remembering Math from Highschool

I've recently decided to apply to business school. Not because I don't love design! I do. I've just been thinking about what kind of job I will have when I graduate and I just don't think production-type work will be what makes me happy. I would rather work on the overall concepts and manage projects as a whole. Business/Design job... if possible...

One of my main problems is the fact that you have to take a standardized test called the GMAT to apply to b-school. I got a book at Barnes & Noble to help me brush up on my math skills, seeing as I haven't done any real math in, oh, 6 years. Unfortunately, after trying a couple example problems, I realized that I not only have forgotten everything about algebra, I can barely do long division! So I'm taking a 9-session Kaplan course to help study for the test, which seems to be helping a lot.

My goal is to get into Ohio State, but if I don't, my GMAT score stays good for 5 years, so I can see where Matt gets into dental school, and plan from there. If I do awful on this test, oh well. At least I can say I tried.
