As an added bonus, there were several BSAC divers on board, including members of Bicester BSAC, who were having a branch holiday. Steve encouraged the other divers to give me marks out of ten for my briefs. And, towards the end, my scores improved from the sort of thing Norway receives in the Eurovision Song Contest, to what could be awarded to someone who might actually know what he was talking about. The course had lasted for three punishing days, but I felt I had finally made the grade. Entire courses last 3-4 days.
Divers can also undertake sections of the course separately.
