I would like to assign a quiz to students to take that is for class preparation, but I would like the score to be based on completion. As far as I can tell:

• Graded Quizzes report the score earned on the quiz
• Graded Surveys award fixed points for completion, but do not show the student right and wrong answers

Is there any way I can accomplish this? For example, if the quiz has 10 quiz points, but the student earns 7, I still want to give them a fixed number of points toward their final grade. With Assignments this could be accomplished by specifying that the grade was Complete/Incomplete.
