"I think it's a good way to be able to have tests on the computer without having to put the computers in a high security mode (even if you can also do so with Exam.net!). The chat feature is also a great advantage; instead of walking around the classroom whispering to the students, I now exclusively use the chat, which gives a completely calm classroom at exams + I can also send out a message to the whole class about any question I get from several students, how much time is left, etc."
