I'm looking for a question type for physics problems mainly. The idea is that the student can select the first answer from a dropdown menu. If its correct than he will get a point, and the next question of the problem will be revealed. Otherwise, he will get minus a point/number_of possible_answers, and he can try a different answer. When the student finds the correct answer, a new question will be revealed, until all the questions are answered correctly and the final solution is found.
I suppose there isn't a question type like this.
But I would like to know, if you know something on this.
