The Guardian reports that the new GSCE science exam is "controversial" because of suspicion that the questions have been "dumbed down" with multiple-choice questions that are insufficiently challenging.
They offer a sample of eight questions that a reasonably educated person could answer correctly while half-asleep and thoroughly intoxicated. There is of course no way to know how representative the questions selected by the Guardian are.
Take the quiz and see what you think.
There is a much more entertaining quiz offered by one of the British universities for Christmas break. It's lost somewhere amongst my thousand bookmarks; I'll see if I can track it down for a future blogpost.
