Were the options along the lines of weather, fuel, flight plan...?
I had the same question in flight planning when I sat my exams. Left feedback but my mark never changed so either I guessed correctly or they didn't read my feedback. Not sure how it works but I always said to other candidates always leave feedback on ambiguous or poorly written questions. The thinking being that the more who leave feedback the better the chances of a question being reviewed. Or so you would think...
I did have marks in two exams go up by a few percent so it does happen.
Some of the questions are a joke, though, and candidates shouldn't be having to flag poor questions up for review. Especially when you're forking out close to 70 quid just the sit the bloody things.
