I read the article. It doesn’t mention if the student was required to do any additional supporting coursework. It only says she was accepted to the program. My Ds were accepted to the grad program, (so was D2’s friend)but their acceptance required them to complete a number of undergrad engineering courses before they would be allowed to continue with master’s level coursework.
While many engineering master’s program will accept non-engineering degree students into their program, they all typically mention it will add additional coursework to “catch up” students with engineering fundamental
Like this program at Boston U
Here’s MIT’s statement in the topic: science may gain entry.
To qualify for a graduate degree, applicants are expected to have at least an
undergraduate-level exposure to most of the core MechE disciplines (solid mechanics,
dynamics, fluid mechanics, thermodynamics, heat transfer, materials, control, design and
manufacturing), and to be familiar with basic electric circuits and electromagnetic field
theory. Those who are deemed deficient may be asked to make up courses in certain areas
before they graduate. The make-up courses may be at the undergraduate-level (in which
case they are relatively elementary and usually cannot be applied toward graduate credit),
or at the graduate-level (in which case they carry graduate credit).
Stanford has list of required coursework and competencies for those wishing to enroll in the MSME program ( Mechanical Engineering Graduate Handbook (SUNetID required for access).
