RonFrank has a good point, you better see what your LDS will offer before you get too set. My LDS announced that besides the Deep and Navigation, I would take 1. Boat diving 2. PPBuoyancy and 3. Underwater naturalist. That day amounted to "Here's the boat, yes you're weighted correctly and there are the fish".
But I guess it's more common than not. I'm growing to appreciate our LDS training more over time as I read stuff like this.
For our Peak Buoyancy we were required to do all sorts of UW drills following the Instructor through hoops at different depths, hanging motionless, swimming upside down through hoops. I was fun, and a bit of a challange to get it right.
Our altitude dive was just a dive, but then altitude diving is about theory and how to assess and adjust BT at altitude. We discussed the altitude, and logged the dives accordingly.
The Night dive we did was also a bit skimpy other than the fact we did out and back Navigation. Deep is just that deep. You do some drills at the surface, and then again at depth to judge the narc factor.
Our Navigation dive was good. We had to do out and back, squares, triangles, and keep track of kick cycles. Good stuff, and I would HOPE that most instructors do a LOT more than here's the boat, their's your weight, there's a fish, have fun. IMO that is JUST LAME.:06:
