MathQuiz is a practical work I did with my boyfriend on our Programming 1 course using C# and Jypeli during the autumn semester of 2018.
In the MathQuiz, you need to solve (more or less) tough equations with or without a timer, depending on the mode you choose. Both modes have their own point lists for top 10 scores.
