Before you start
- It runs like an online exam: one question at a time, with a palette showing what you have answered, skipped or marked for review.
- The clock starts when you press Begin the test, after you have read the instructions, and keeps running even if you reload or leave. At zero, your saved answers are submitted.
- The test opens in full screen where your device allows it. Leaving full screen or switching to another tab or app is recorded with your attempt, and whoever set the test can see it. Your own count shows at the top of the test.
- Your score, the answers and the explanations show when you finish, with where you stand among everyone who has taken it.
