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.
