Selling on a $5 price for quiz question seems much more than I expected.
After all, its free material all over the internet.
Dont really expect to learn anything from a quiz, but to remind of things.
To be honest, I was quite surprised it is "Paid App".
- codezero 13y agoThe cost per problem is a lot lower than books that offer the same content, so it seems reasonable.
