After OW class, I felt competent to dive in the conditions in which I received my training. I dived with my buddy (who was 10 dives ahead) in a quarry and in the Keys. The quarry was easy in spite of poor viz because you couldn't really get lost, no currents, surge or having to find a boat. The Keys presented more navigational challenges because some of the sites were spur and groove formations making it more difficult to keep track of your position and then find the anchor line. It was shallow enough to surface and take a bead on the boat. I then went to Belize, Roatan and Cozumel and gained a lot of experience.
When we took AOW after 60 or 70 dives, our instructor tried to challenge and task load us. We did the deep and navigation dives first. The 3rd dive was PPB where we practiced buoyancy exercises and were challenged to naviage while maintaining neutral bouyancy (not moving up and down the in the water column). On the 4th dive, we had to map a wreck which tied everything in. It was deep - 100 feet to the sand - so we had to manage gas. We used nagivation techniques measuring the wreck with armspans. We had to log this data and draw a map while underwater. The last dive was a night dive where we had to navigate with a compass while maintaining buoyancy and using the flashlight.
I think a diver grows in skills and confidence with a combination of classroom and experience, particularly experience where you're not dependent on a DM or instructor.
