Multi-level quiz scoring
I am sure the question has been asked before but I cannot find an answer to it.
I have a fill in the blank quiz. Students are given several attempts to answer correctly. At the moment when they answer correctly they get the maximum score for the question (10 points - set by magic as far as I can tell). Instead, I would like them to get a score based on the number of attempts it takes them to get it right (e.g. 1 attempt = 10; 2 attempts = 7; 3 attempts = 4 etc...).
