How much you get out of an advanced course depends on the instructor. I recently took my AOW, and I had already done all of the dives required previously outside of navigation. (Deep, limited vis, boat diving, etc. I had already performed). So when I told my instructor this he said OK, and added alot to the course so I'd get something usefull out of it. I told him where I wanted to go with my diving someday (technicals, wrecks and caves), and he's a certified cave diver and what not, so we did alot of extra's in that area such as hand signals, flashlight signals, he gave me alot of tips on technical gear setups, redundancy checks with your buddy above and under water, creating a dive profile in my head throughout the dive from looking at time, air left, and depth, etc. and alot of other information like that.
I told him I was weak on navigation becuase that's where I had the least experience, so we focus'd alot on that as well.
We practiced most of it routinely while we were under, so I ended up taking quite a bit away from the course even though most (if not all) of it was above and beyond due to the circumstances and the fact that I had talked to my instructor before hand and told him what I thought I was capable of and what my plans for future diving were, so he tailored the course for me. It should be a learning experience, not another card.
Granted, I was lucky enough to be in a 1 on 1 situation, but with any luck in your AOW class you should get alot of 1 on 1 instruction if the situation permits. Most of the AOW classes I've seen out of my shop have been pretty small, with a divecon leading alot of the dives.
