Yes one has to read the questions carefully as some are misleading.
Not to establish skill levels but to wash out the 'inappropriate'.
That is the military way of doing things, because (in a professional air force in peacetime) you get 100s of applicants for every flying job. So you have to apply some pretty crude techniques to weed out the huge majority.
Unfortunately when this is carried through to the company which you joined after your RAF career in order to preserve your civil service pension (called the CAA) you can't chuck out so many people anymore, but nobody thought about changing the basic techniques.
That's why we have the stupidly elitist IR ground school - a huge memory exercise.
This problem is everywhere, not just in the UK, because the aviation regulatory world has always drawn from the air forces and the airlines (esp. the national flag carrier).
