@Heston,
The relevance here is to get the big picture mind set. It really makes no sense to enroll in aviation training without understanding how the rules and regulations Impact aircraft flight envelope.
Essentially, what the Staff is saying, is to get informed in advance of the training and pass the exam unfront to alleviate the obstacle before commencing with the training.
It is my experience that such a move reduces the workload and enables better focus on learning how to fly.
