1. Is this just for fun or self-learning, or is it something where you really want to prevent cheating?
Why I'm asking: A simple model would be to have two pages, one (using Javascript) where you pick answers and then click something at the bottom to reveal your score, and a second (unchanging) page that explains each answer. This could also be combined into a single page where you see the explanations once you click.
However, unless you do extra work to disguise what you are doing, it would be easy for them to figure out the answers by looking at the source code of the page.
If it's just for fun, that's not an issue.
2. Do you want to learn how to create a page like this, or are you just after the finished result and hope somebody will build it for you?
