In my opinion this quiz is scientifically reliable and can be recommended to students and teachers, it is intuitive and usable. A layout is focused on ease of use, and ease of reading. The quiz can be attractive for teenagers. Consistent design allows the user to focus on the message. The resource could be more visually appealing to students and provide answers to exercises without logging in.
