Quiz and negative gradings

Hi Tim,
more and more we are asked, why moodle does not support "Negative Gradings" ins quizes.

f.e.:

• This question is only full completed correct
• Negativ percentages from one question, will be calculated as negativ in the quizmodul
• you get + % for correct questions, but if you dont click on this, this answer is wrong.. and the penalty is ...

is this difficult to solve Tim?

regards Peter
