"Did you fail by much and in the areas you expected?"
Quite a bit, and I've no idea - never get told what questions I've got wrong for any of the exams I have passed at less than 100%.
I'd spent the week prior to the exam re-doing the Pooley's mock exams, and did well on them all. Sadly the exam didn't ask for any plotting or identifying things on charts, it asked purely mathematical questions to really test use of the whizz wheel for fuel calcs, speed / temp calcs etc. Stuff I simply hadn't practiced enough as I believed the exam would be testing my ability to plot a route and produce a plog whilst knowing all the stuff to avoid... what I thought of as navigating!
