“The fact that Brandeis offered both in-person and online graduate programs, but only in-person undergraduate programs, could allow a jury to infer that Brandeis reasonably expected plaintiffs (both undergraduates) had paid tuition in exchange for in-person instruction,” the judge wrote. “Finally, although classes might be moved with some frequency from one meeting place to another, a jury could find that this did not disturb a reasonable expectation that plaintiffs paid tuition in anticipation of classes meeting in-person somewhere on campus.”
