I am thinking of changing my quiz requirements to average score from highest score. Students will have two attempts. Does the system average all attempts or all submissions? I am trying to avoid students asking for re-takes. If the student does not submit a quiz attempt due to ISP failure etc. I want the system to record the score of the single successful attempt not the (single+0)/2. Similarly, if the student has a perfect score in the first attempt and does not take the second, I do not want the score divided by two! Where can I find out how the math works?
