I'm wondering if this is possible in quizzes in Canvas. I will be providing 17 total quizzes in my course, but I want only the top 12 scoring quizzes to count, and some students may not take more than the 12 that I require (they can take more, but they're not obliged to if they are satisfied with their scores on the 12 they take during the term). 

Would simply telling Canvas to ignore the 5 lowest scoring quizzes work? Would it work if a student only took, say, 13 of the 17 total quizzes or would it end up dropping the 5 lowest scoring of the ones the student took, and then only counting the highest 8 scoring quizzes? 

hoping my question makes sense. TIA!
