That was me at the beginning of my studies - I wasn't sure how to set up the games at the beginning. I recommend going through the LG section of Khan Academy! Super helpful and free!
Most of the sources of info I know of require prerequisite Econ knowledge but I think if you learn the basic laws of supply and demand, you’ll be in good shape. You could use khan academy for that!
I also saw this - not sure where these questions are from, but I couldn't find the questions anywhere online, so they seem new. Maybe it has something to do with Khan Academy moving their materials to law hub?
