我會這樣看:
Duke, TSE M1都是medium class size的taught master, 拿信的難度相約. 唯一不同的是其connection的effective location不同.
而duke比TSE明顯優勝的, 是其global reputation, 這個只對找工作有用. the tuition only worht it if one realized the return on human capital through leveraging the great rieputation of school in the private job market. Academics have a much longer "Duration" and lower expected return, and I will doubt if it really worth or not for those who are 100% sure to PhD.
