The nature of some topics, especially in the higher end courses, do not lend themselves easily to multiple-choice-style answers. Sketching Graphs and Geometric Proofs are good examples of this. In these cases, once the worksheet is completed, the student views the detailed worked solutions, to their own understanding of the steps in solving the questions. Students use the solutions and marking to be able to grade themselves appropriately. Please note that the vast majority of lessons contain multiple-choice answers, and that the self-graded lessons are mainly found in the Algebra and Geometry course.
