Advanced Open Water is 5 days in the classroom/pool and 5 open water dives.
One dive must be a Navigation dive (actually navigate a square and triangle instead of just the "out and back" covered in modern Open Water).
One dive must be to 100ft (standards don't allow the class to go below 100, so the instructor will usually have everyone kneel on a hard bottom at 92-95 and everyone holds their depth gauge/computer as low as they can, but per tables, 91ft is a 100ft logged dive). You'll look at a color chart, do a math problem, we played a couple of games of Perfection...
This was all done to reveal the effects of narcosis, as well as show how colors go away as you go deeper. Sometimes the instructor will show how a styrofoam cup turns into a shot glass, or might take a tennis ball down to show the effect of pressure.
The other three are elective dives, and they may be applied toward a "specialty" certification such as wreck, drysuit, night, etc...
In my class, we did a wreck dive, a night dive, and a drift dive (Drift dive down the Colorado from Laughlin to Bullhead!).
I took the wreck specialty a month later, and since all 5 of us were in the same AOW class with the same instructor, when conditions got blown out on our 2nd wreck dive, we were able to complete the specialty with only 2 dives for that class. One dive was to be "survey", one was to be mapping, one was to be penetration (exit always visible).
Our penetration dive was on the HCMS Yukon. Conditions blew out and we couldn't do our mapping dive on the Ruby-E, so the next weekend we did a mapping dive on a barge off the coast of Laguna Beach, and we used our AOW dive on the "SS Minnow" in Lake Mojave as our "survey" dive.
Nitrox is one classroom and two dives, not sure of PADI allows it to be combined into AOW or not. PADI was very resistant to Nitrox for many years and even once referred to it as "death gas"
My Nitrox cert is through NAUI, plus I have GUE Tech Fundamentals.
