BusinessWeek has a useful article here for undergrads about using the years before business school to position themselves for B-School admission. Given that the average MBA has about 5 years of work-experience before they join school, this article (first of a series) shares a year by year plan for prospective students.
Even for people who plan to do their MBA sooner, this is a great start-point which promises to touch on key prep issues like the GMAT, networking etc. Hope you find it useful!
