Everything below is still accurate revision material for Topics 3 and 4, but the exam structure it describes is not yours. Switch the course format at the top of the page if you are in an in-person section.

On the day

  • 14 questions.
  • Taken in class under LockDown Browser.
  • The ALEKS Exam Review that opens the week before is the same length and the same format as the exam itself. Treat it as a dress rehearsal, not a study guide: work through the material on this page first, then sit the review once, cleanly.
  • A conversion table is provided inside the ALEKS question for any item that needs one. You are not expected to have the factors memorised.
