Oh that would be a great motivation tool for any teachers using this to teach students how to type. they can compete with their classmates. Perhaps expand this into adding tools to help typing teachers motivate their students and generate progress cards/etc.

On a separate note, my school had a special class just to force kids to learn typing and their software was extremely boring to use. you should totally explore approaching school districts to see if they would be willing to purchase a premium license. I know my school had two computer labs of 30 computers each so that is like $600 in premium licenses per school per year, assuming you use your current business model. I forget which software they used for their typing class, but they definitely paid money for it. So I'd imagine they would definitely at least consider any proposal you send them. You could make a pitch on teaching tool to aggregate student data into report cards, ability for students to use the software at home given it is online with a free tier, and etc.
