I did an old (2006) UK Intermediate Maths Challenge paper today, and got 105 marks (it's the damn circles that always confuse me ). The two mark boundaries I've found (on the UKMT site and on here) that with that score I'd get into the next round (I'm slightly confused by all the Cayley, Hamilton, Kangaroo etc options). However, when I took the paper last year (2010) I only got bronze. I know I've improved since then, but I didn't think I had that much. Does anyone have the mark boundaries for the 2006 paper?
... and the ones that won't
