Each question shows an analogue clock and a short story: a bus leaves, a class starts, a film begins. First read the time off the hands, then move it forwards or backwards by a number of minutes.
The minute hand always sits on a five-minute mark, and many questions cross the hour, which is where most mistakes happen. The answer is chosen from a list.

Numbers&Me is free. Sign up to practise more, or set it as homework in under a minute, and it marks itself.
