Sounds like the AOW course I took, but I was on the other side of this story - I was hoping to get rushed through. I had ~100 dives in before taking AOW and was a water person before getting into scuba. Took it at a dive resort, so fully expected to go through it quickly with little real instruction - got more out of reading the manual. I also have no doubt that had I taken AOW at my LDS, I would have gotten more out of the course, like actual instruction/feedback.
Whether you take PPB or not, or any other options being offered in this thread, diving more and experimenting with some different tips being offered earlier, is the best thing you can do, IMO. Just my own self evaluation here, but I feel like I became better at being where I wanted to be in the water, just by getting more dives in, even though those dives only came when I went on vacations. I started carrying a small camera on my 7th dive - being able to stay in a good position and stay there was a concern at that point, but it wasn't long when I felt I was in position to take a picture, able to move in or back away without disturbing anything or anyone around me, without even thinking about it. Same with swim throughs. Just came with doing more dives.
Don't always like analogies, but after the required 6 hours of driving time in a driver ed course (in Indiana) and the classroom time, it doesn't make someone a great driver even though they may have had a great instructor. What the individual does afterwards when not in the class is going to make the difference how successful they become.That's true with driving or diving.
