Question

A user can request a quiz for the system. The system picks a set of questions from its database and compose them together to make a quiz. It rates the user's answers and gives hints if the user requests it. In addition to users, we also have tutors who provide questions and hints. And also, examiners who must certify questions to make sure they are not too trivial, and that they are sensical. Make a use case diagram to model this system. Work out some of your use cases. Since we don't have real stake holders here, you are free to fill in details you think is sensical for this example.
