I agree with Tom Ace don't just rely on the feedback to get you through. Yes there is a lot of padding in there but when you do get to the job interview depending on who it is, you will find that Met, POF and JAR Ops can figure heavily in the tech questions and these won't be based on feedback !!!.
Also in the day to day job, Performance and Met are an everyday occurence.
Gen Nav was mine as its just to easy to run out of time in the exam. (Damn Whizz Wheel)
Good luck with it
