I'm just speaking as someone midway through the ATPL process.
The met and PoF seem definately relevant, even if not now, but some of the subjects (eg HP) seem to be there to pad out things. Dont get me wrong - I take in the subject but I don't think doing the exam will improve my ability regarding stress, CM etc....but I can't really say until I am putting it into professional practice.
Interesting to hear all your experiences and views.
