Don't know if this would help. If you create a True/False variable for each question, then when a question is selected the variable would change from False to True. Then instead of using a question bank, create a scene for each module with all the questions for that module. When the user have gone through all the modules, create a review page to allow the user to return to the individual scenes. Create another True/False variable for displaying cumulative review, if the user is visiting the module via the review page, the variable would change to True. Then for each question in module create a trigger to jump to the next question slide when the timeline starts on the question slide if both the question variable and the review variable are false.
