This resource can be a great way to review Demand/Supply. I really like the questions and the quiz style that you used. However, I would suggest some improvements. Firstly, I'd suggest the addition of images to the presentation, as it provides better comprehesion for visual learners such as myself. Your graphs are great, but could work better if dialogue boxes were connected to them to better demonstrate how and why the arrows move up or down. I also find that the amount of text per slide should be downsized.
Links work correctly, but I feel like a "back" button, as well as a "home" button, is missing. It would be helpful in case the student wanted to review the info before answering the questions provided.
