I think it would be a great idea if instead of putting a studio quiz in the assignments option that we could use the quiz option that allows us to be able to time a quiz, allow a single attempt, and have the grades feed automatically into the gradebook. Also to be able to assign point value to the questions. For example: If I only have 10 questions in the video, but I want each one to count for 2 points.
As of right now, in the assignments page options they are allowed multiple attempts, and each question is automatically assigned a 1 pt. value. And while I have limited the time the assignment is open, it's still not restrictive enough on number of attempts.
