I had a go at it on the weekend. I skipped the ABCD square question because I had no idea how to do it. Got everything else though, just silly errors here and there. Full marks on the last question, which I was very happy about (although I did have to think for a while about the last part of a)).
I thought the multiple choice was surprisingly hard. All my school exams had fairly easy questions, so it came as a bit of a shock. Overall though, it was easier than I'd expected. There was nothing that was really "out there", so to speak.
