I'm a student in teaching mathematics and interested in a certain kind of quiz report. It would be great, if you could categorize wrong answers of the multiple-choice test to several "kinds of mistakes". I couldn't find this possibility in moodle. I have some basic skills in php and MySQL but never wrote a plugin. So my question is, if it is possible to write a plugin, which solves this problem. My first idea was to write a new question-type, called "Multiple-Choice with categorizable answers". Is this an approach that makes sense?
Thank you for your help.
