I only got one offer from Drexel last year. The reason may be low GPA at CU, 3.67 for my MPhil. I had one Babson Entrepreneurship Conference paper before application. However, when I came to Drexel, I found that the professor did not place attention to my conference paper.
Anyway, Drexel has two active chair professors, John Schaubroeck and Jeff Greenhaus which are more than enough. My publications are more important than university's ranking.
