Suggestions to improve the Quiz Factory

Question

The quiz rating system should be turned into a ‘challenge practice’ area, where users can gain small amounts of XP for answering questions correctly, but without losing XP for incorrect answers. To make it challenging, there should be a time limit and you should only be able to submit one answer per question – if you give a correct answer you get the XP, a wrong answer and you are moved to the next question.
A question would be approved once enough correct answers had been given.
