I really liked the paper, the maths involved wasn't too difficult however it was a difficult paper because it was very left field and required us to interpret the questions and figure out exactly what they want us to do. I found that nearly all the questions at first left me thinking WTF?!?!? but after I had a think and tried a few things they all seemed to work out nicely and made you really think. You really had to know the concept not just the application which sets the rote learners apart from the people who just "get" it 108+
