I thought it was a tricky, but very fair paper that rewarded those who ventured outside the pure zone with an easy mechanics question (11). I also thought that q12 was not hard, you just had to get your head round what was going on. I reckon the grade boundaries will be about average, probably 67 for a 1. Using induction really helped with q8, which was a little harsh on the non-further maths people, but all in all, I felt that the question setters did a good job.
