PA, at the risk of sounding abrupt your problem is that you do not know the subject.
You are trying to pass the exam, understandable, but your emphasis seems to be on the exam issues rather than understanding what the exam is attempting to achieve.
How are you going to cope when you get your rating and you have your renewal, 20 random questions at least and you need to get at least 16 of them right, every 12 months.
As an example, would you rather send one of your kids to a surgeon who has studied just to pass an exam or to one who knows his profession.
Change your attitude and learn the subject and you will find that the exam is easier.
