Right now I am 21 years old living in Canada, but i want to try for the top 20 b-school in US. My questions are whether 1) I should apply to the b-school given my par level qualification2) what school u guys would recommend given the city and the general econ, ( i have not talked to anyone who have gone to the schools except for Columbia and Yale, which i felt they are v. good schools)Thanks in adva
