Looking at it logically, any exam with three levels. The difficulty I thought would always be ascending.. People writing each level have cleared the previous level, so its more stiffer competition as you go up the levels. Atleast thats how I felt.
And my first failure came in level 3 last year with a band 10 - thank god I crossed it this time around
