College advice, i have my credentials and goals listed?

It doesn't look like you should have a problem getting accepted into a major at Ohio State... but once you are in college you will just have to maintain excellent grades in order to be able to get into Med School. I'd say you want to try and maintain a 3.7 GPA or higher in undergrad.. but you can decide your major once your there, just start out as undecided then declare one once you've met with a couselor.
