Here we have the research universities near Chicago (flagships are available under that heading), to see if they are like the University of Illinois Chicago. Purdue
looks good (53%), but figuring its percentage was far more difficult
than usual, due to the way its courses are displayed. The University of Iowa is almost as strong at 50%. Michigan State is substantial weaker at 34% and University of Wisconsin Milwaukee
is very low at 24%, like the big city schools, but not in a big city.
The strength at Purdue and Iowa State is attribuable to their
emphasis on engineering. The University of Illinois Chicago is not an
engineering school, but stands out apparently simply due to the
importance of Friday to its faculty and/or administration.
