University of Illinois also runs an online MCS program, similar to the Georgia Tech one. The curriculum is very comparable to the on-campus degree, and is supposed to take 2 years or less, I believe
The whole program is ~20k. Each course is ~2k. There are some additional fees like exams. The previous semester was probably ~3-5hrs per course. This semester my most difficult course is upwards of 10hrs weekly to complete labs. This is not including actual lecture content and quizzes (probably another 5hrs).
Obviously that's a completely different program & faculty though.
