Choose your chapters
- Questions come in random order, about half concepts and half problems.
- Problems get new numbers every time, so you will not run out.
- Your score counts only the questions you answer. Skipped questions do not count.
- Your record for each chapter is saved on this device, so you can see where you stand each time you come back.
- Answers are also counted anonymously, with no names or logins, so Professor Moon can see which topics the class finds hardest.
