Is there any way to drop points in a quiz similar to the way an assignment group can be set up to drop a certain number of scores?

I have a situation with an instructor who wants to give quizzes worth 10 points however, there are 12 questions. Each question is worth one point. He would like to be able to allow students to miss up to two questions but still get the 10 points (100%) for the quiz. If the student misses a third question, they get nine points, etc. The caveat to this is that if a student answers all 12 questions correctly, they still only get 10 points. The extra two points for the additional two questions are dropped. There is no extra credit.

Is there any way to accomplish this?
