Multiple-choice tests come in many different guises these days. This one is more straightforward than most - up to 50 questions on 'O'-Level/CSE Physics. If you get them all right you are rewarded by seeing a little man walk across a desert to get a coconut from an oasis. I would have thought that by 'O'-Level, this kind of reward was a little superfluous.

Two batches of 50 questions are provided, covering four main branches of physics. Three alternative answers are given for each. I disagreed with a few of the right answers, but that may be because my physics is a little rusty; on the whole, the questions are quite well designed.

Three different "games" are offered: a fixed time for answering each question, a mind-master test where you have to answer as many as possible in two minutes, and an exam in which you have ten minutes in which to answer all the questions. At the end of each, questions answered wrongly are listed together with their right answers. There is also a revision mode, in which the questions and answers are displayed.
