I want to allow a user to revisit a quiz slide they have already answered and change their answer if they shoose to do so. They have already answered the question, and have been notofied if they have answered it correctly or incorrectly. A few questions later, they decide to return to that question and c hange their answer. Is there scripting/advanced action/something that can be doen to allow this?
Not with the default quiz slides (can be done with custom quiz slides). Reset is only possible on Quiz level, and results in having all answers cleared on all quiz slides.
An alternative could be to use the Submit All feature (Quiz Preferences, Settings). That will allow free navigation through all questions, with the possibility to edit the answers. Only when the learner decides to be ready will he click the Submit All button and transfer all answers at once.
