How much do you really know about the facts and figures behind this election campaign? Here's your chance to find out. Below there are 10 questions on a number of subjects which have been discussed by the politicians and the media over the past few weeks. The answer to each question is a number, but you aren't expected to know it exactly. To score points, you just need to be able to say roughly how big the number is, by giving a number you think is smaller than the correct answer, and one you think is bigger.
You get points if the true answer lies between the numbers you give. The closer together are your two guesses, the better your score. But you will lose points if the true answer lies outside the range you give.
