HES admissions are risky.

You already have free access to Harvard museums as a Cambridge resident : ) I honestly don’t think HES is the best choice for a master’s in CS, but here are their majors Digital Media Design,
Information Management Systems ,Software Engineering

MIT does not seem to have a terminal master’s.

Gibby posted Tufts’ part-time program. Looks great.

BU has an MS program in CS in both the CAS/GRS (BA, BA/MS, minor, MS, PhD) and the evening Metropolitan College MET (BS, accelerated degree completion program, UND Cert, MS, GRAD Certs)

Northeastern’s MC n CS accommodates those who work http://www.neiu.edu/academics/college-of-arts-and-sciences/departments/computer-science/programs/computer-science-ms

If management is the goal, does your employer prefer an MS in CS or a business degree?
