Currently, for any questions that the learner got wrong, the learner is submitting a new attempt, the previous attempt answers have been saved, however when the new attempt is submitted with re-works for the questions required, the tutor has to re-mark the questions the learner has already got correct for the quiz to be graded again, which is time consuming.
Hope you can help, thank you.
I think the problem is your manual marking. I am not sure you can do what you want when you manually grade. For automatically graded questions, I would recommend Interactive with Multiple tries but when there is manual grading involved, I am not sure that would work.
I think that if you want to let someone rewrite their answer to an essay question, you might be better off using the Diary or Journal activities. Both activities are ideal for this with my "bias" being towards the Diary activity since I maintain it. 😁
