I would like students to have the option to take 1, 2, or 3 different quizzes on a particular topic where only the top score is counted in the grade book. If I drop the lowest 2 in a category, that doesn't work because then they have to take all 3 to get any score at all. I'd like only the highest score of the 3 different quizzes to be counted. That means some students may take 3 quizzes and some may take only 1 and all will have a grade display in that category.
