Draw and explain the use-case diagram, activity diagram, interaction diagram for the following: Consider developing a desktop-based framework to assist people in preparing for a certification exam like "SE@exam". A user can ask the system to create a quiz for them. The machine selects a group of questions from its database and assembles them into a quiz. It assigns a score to the user's responses and provides hints if the user needs them. We have helpers that give hints in addition to users. And also examiners who must certify questions to make sure they are not too trivial. 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 required for this example.
