This program has strong emphasis on statistics and math, and lack of resources on finance, partially because JHU has mediocre business school. Most of the professors are very helpful, however, some of the professors are not helpful at all: they literally read the PPT and do not care their students are actually learning or not.
Second, this program lacks a students diversity: almost 99% of the students are from China, only one or two are from other countries. The workload of this program is considerable: 4 courses every semester and 3 semesters to finish the degree, and some of the courses are very helpful in quantitative field.
Most importantly, this finmath program at JHU does not have connection at all: it did has connection with Fannie Mae about 3 years ago, and connections are gone, students are suffering from finding internship/full time jobs. According to my knowledge, only few students get offer from big bank. Also because its awful location: Baltimore, it has made students even harder to land intern/full-time.
If I give any advice to students who are applying to MFE programs, it is all about connections and location. Ranking of the university is the last thing you want to consider.
