It contains a graduated set of over 1,000 problems starting from very easy and working up to very difficult levels. Each problem contains a short description and an image to help visualize the problem. Problems adapt to the skill of the person answering problems, grade levels cannot be increased until 5 correct problems in a row have been solved. The tests concentrate on understanding, spatial reasoning, and problem solving rather than math rules and theorems.
