How the exam works
- One question per screen. Once you move on, you cannot go back to an earlier question.
- You have 55 minutes. The timer starts when the exam opens and keeps running, even if you leave the page. When time runs out, the exam is submitted with the answers you have saved.
- Your answer is saved after every question, so you can resume where you stopped if your connection drops.
- The exam opens in full screen. Leaving full screen is recorded and the timer keeps running.
- If focus leaves the exam, for example to another tab or window, you see a warning and it is recorded. Warnings do not end this exam.
- Copying, pasting, printing and right-click are turned off during the exam.
The exam needs a laptop or desktop computer with a window at least 1024 pixels wide.
