I took the FT pre-experience MiF courses, and selected the 30 with the higher international mobility. I then removed the 10 with the lowest employment, to focus on schools with 94% or higher employment. I then removed the ones with the fewest international students, to focus on the schools with 70% or more international students, to lessen the effect to schools sending domestic students abroad. I have ranked the 10 best schools below, by average salary.
