Right know there are actual students at EPFL who are taking the Functional Programming Principles in Scala course, using the same web site that random joes like me are using at the same time. So for me it's not an actual college, but it is for those students at EPFL. They have no choice but to enforce academic honestly rules, given that real students at a real institution are involved.
It makes sense for EPFL to use the course lectures and quizzes to help the students, but it makes absolutely no sense to use it for the grading part. It is trivially easy to make a second account, take a quiz, and just answer randomly to be able to see all the correct answers. It's absolutely absurd to not have a totally independent grading system.
