DSMB is the Delayed Surface Marker Buoy. It is a new standard specialty. There is no student manual for it, so I wrote one for my students (the VP of products, Ted Moreta, wasn't interested in it unfortunately).
So for the PPB, I'd have my students frog kick as part of traveling over a sensitive bottom (silty), and they had to do so smoothly, and everyone has needed practice sessions before moving onto the next one, navigation. I felt quite strongly that in order for a student to be task loaded with navigation, they had to be able to fin smoothly and have good buoyancy and trim, otherwise students have a tendency to rise as they go fin. For the night, students had a lot of difficulty with navigating a triangle, as they needed to keep their depth constant, as if they followed the bottom, they'd wind up nowhere near the starting point. Deep has weak requirement, so I didn't do anything special there. DSMB, they had to deploy from midwater without much change in depth, and when ascending, they had to stop, and keep the line tight when working through the performance requirements. All that, for a relatively new diver, that's just not happening in 5 dives.
I'd have a good conversation with the dive op you choose about your expectations and their standards for training. I guess you want to be challenged and work hard for improving your diving skills. Sounds like to me that GUE fundies/UTD essentials/ISE basics are better options, but logistics may prevent that.
Now that's funny! HAHAHAHAHA!!!!! Oh, the image in my mind: wind blows exam into the water. Instructor looks at the papers fly away, thinks "oh s__t! Now what I'm gong to do? .... I know!", and says .....
