I have multiple questions where the user watches a short video and then answers a question. I would like for them to be able to watch the video again if they get the answer wrong. And I need them to only be allowed to answer once.
I know this can be done by adding the same video in another layer or slide. However, my projects are in Sign Language and usually have about 50 videos to begin with. Duplicating would put that number at a 100 which is too much for our computers.
