Rback,
Live by the gouge, die by the gouge. The gouge is what you use after you've done your readings to reinforce what you've read. It includes notes, flashcards and study aids. The icing on the cake is when you take a critical eye to the gouge and verify it's accuracy. If you do this, you'll find some erroneous and dated material, and in the process you'll become the expert in the material that you need to be to not only succeed, but succeed well.
If you don't, you'll get the rote memorization of facts and figures, which, if taken out of context, will show up in the table top briefings, check rides, and shotgun stand ups and leave you looking like you have a very poor grasp of the material.
