Captain
Final Approach
Although pithy, I think there is a flaw in this line of thinking. The situation isn't binary--you can study for the test and be an inquisitive pilot. The consensus here is basically that the written isn't 100% reflective on the ability/capacity to be a pilot.
Just as you say it's no good to just study the answers to the test, it is also no good to ask your CFI questions but get a 50 on the exam
Studying for the test is different that studying the test.
If you have a big red book in your library I'd say you are not an 'inquisitive pilot'.
