Track My Progress is a computer adaptive test that uses a question bank of over five thousand questions. During a test Track My Progress chooses the difficulty of the next question based on how well the student answered the previous questions. For example, if a student answers three medium questions correctly, the test is then going to give more medium and hard questions and fewer easy questions. However, if a student answers the medium questions incorrectly, the student will see fewer medium questions and more easy questions. This helps explain differences from one student test to the other.
