In university courses, is it possible or good habit to ask help for homework exercises one can't solve? I mean, someone might think it is cheating but on the other hand, should a student be stuck in some particular problem for days?
The course I take is about version control on git and there are questions in an online system. One question has six different true/false questions, where one can choose on different alternatives. The system has informed me that my answer is incorrect; however, it does not explain why my answer is incorrect, and I'm not able to figure that out by myself.
