Are you at Operational?
I wouldn’t stress to much mate, it’s a really wide syllabus and they often throw a few fringe areas in to mess people around. People obviously focus on the meaty stuff so they don’t want everyone writing the same thing…
Know everyone will give you advice but I’d say, after sitting a few (and failing one on one of those stupid fucking competencies - still wrangles), forget about it for a few days there’s literally nothing you can do about the one just gone. You probably need a relax after the past few days.
When your results come around guarantee you’ll be surprised. If you weren’t successful just brush up on those knowledge gaps, they can only ask so many questions.
