How it works

  • Questions are drawn from this assessment's own bank, with numbers generated for your attempt.
  • Your answers save automatically. Nothing is graded until you submit or the time runs out (the server keeps the time).
  • No hints or feedback during the attempt; full worked solutions afterwards.
  • You may use a calculator, the lab and your notes. The assessment is not proctored.
