Normal practice, or a Simulated test
Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 15-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.
How the two modes differ
No account needed
Normal
UntimedEvery question on one page, loading as you scroll. Choose an option and see straight away whether it was right.
- No timer. Nothing to start and nothing to submit. Stop whenever you like.
- Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
- Solutions in place. The explanation, and the video where one has been added, sit under the question.
- Open to guests. Normal practice needs no sign-in.
Real exam conditions
Simulated
Timed CBTThe computer-based test format: one clock, a question palette, and a score the moment you submit.
- A clock that does not pause. 15 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
- Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
- Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
- Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.
