This example of a quiz was taken from a copy of the Radio Times, but there are many similar ones and you can easily invent your own. It would be a good idea to allow the player to select an area on which to answer questions. For each question, the player should input the choice (a, b or c here, possibly more options to make it more difficult) and should be scored on 10 questions.
To pass at the first attempt, you might require 7/10 correct answers, and reduce this by 1 for each successive attempt until you get down to 2/10. The areas offered and the actual questions should be varied for successive attempts.
A correct choice have the response "WELL DONE" but an incorrect one "NO." followed by the correct answer, thus giving an immediate reminder of the correct solution. If the same question come up again later, it should be easy to get it right the second time.
