This is pretty interesting. This year there seem to have been more high scores than the last two. So I guess it was easier?

I did a quick analysis of the data from 2006 (from the graph provided on this thread) and the average (mean) was 58. This time round the average was 55.5 - so in actual fact the scores, on average, were lower - it's just that the spread of scores is wider this year (with some people scoring much high and others scoring much lower than the results shown on the 2006 graph).
Draw from that what inferences you will (but given the approximate nature of the data no estimate of statistical significance can be made).
