The three overall best schools for investment banking placement are: University of Pennsylvania, Georgetown University, and Harvard University.
UPenn is clearly the best finance school in the entire world. They send an unparalleled 3.33% of undergrads into investment banking, with over 50% of their hires going to the very best firms. We note that Harvard sends an even higher % (58%) into the very best firms, which appears to be a minor weakness of Georgetown (only 40% to elite firms).
