I would like to make a multiple answers quiz where partial credit can be given. For example, if a questions has 5 possible answers, 3 of which are correct, I would like to give partial credit if a student gets 2 of these answers correct. Would it also be possible to deduct points automatically for wrong answers? This would be to discourage students to guess the answer blindly.
I think using fudge points, this could be achieved manually, but is there a way to do this automatically?
