Automated grading and extensive commentary provide fast feedback and help students more holistically understand topical relationships. Humor helps make learning the material more engaging and fun. The application uses randomized data and cell layout locations to encourage academic integrity and make repeated practice more value-adding. Assessment results suggest that the application offers challenges and supports learning.
