I bought many books while applying to MBA. I felt that the Business Week's book could be helpful. Yet, I would suggest that you avoid this one since it has nothing except a collection of basic information that you can normally find on b-schools' website. Do not expect real insights on b-schools (it has been written by journalists who do not know much about the real stress of MBA application), no advice to craft powerful essays that will get you in, and no tip to ace interviews!!
