The computer science application includes 2 modes, the first is the test mode which allows you to take a test in a particular topic and tracks your progress through the topic giving you a topic by topic grade, as well as an overall grade. The progress screen associated with this mode shows areas of strength and weakness within the number systems, in the progress screen you can monitor your performance with a graph showing test scores, average score and target grade.

The second mode is the challenge mode, in which you can test your skill in a timed challenge, as the challenge progresses the questions become harder and harder! This mode includes a highscore system.
