From CUNY College to Top Business school, can it be done?

<p>I am from New York and I am in a highschool that is in close assosiation with Brooklyn College. I am able to take a couple of college classes, I can possibly garner around 30 to 40 credits, and I am thinking of going to BC for a b.a in business and then go on to a grduate business school. If I get a good GPA in BC will I be able to possibly get into a top tier business school.</p>
