Multiple choice question. Choose one answer, if incorrect points will be minused
Hello, I want to create a multiple choice question that if the student choose an incorrect option it will substract points of his final mark. For example the correct answer gives 1 point, if the student does not answer the question it will give him 0 points and if he chooses an incorrect option it will substract -0.25 points. Is it possible to do?
Thank you in advance!
