I've passed my ATPL written for quite some time now ;-) , but I can still remember (besides learning all the relevant stuff) reading feedback being an importand part preparing for it.
The JAA ATPL written suffers from (sometimes) stupid questions, bad or weak wording and inconsistency. Reading feedback help's a lot.
As a pilot I like to prepare (a least trying to) using ANY available ressource, preparing for ANY circumstance, so why doing different when preparing for the written?
Have Fun
