One can excuse an OW student from making a poor choice in terms of class or instructor because they lack any context around which to base that choice. However, by AOW, you have adequate context to determine why you want to sign up for the class, and what you expect to get out of it. why do so many people complain about AOW? How You have the ability to evaluate the instructor ... particularly if it's the same one you took your OW from. So much responsibility do you take for not putting adequate effort into researching the quality of the services you expect to get before laying your money down? Would you do put the same effort into any other major purchase you make?

A lot of divers take AOW within their first 20 or 25 dives and have had no regular interaction with other divers or spent time reading forums like SB (yeah, that's a different thread). They STILL have no "context" by the time they are ready to take AOW and no inclination to do any "research."
I would guess that I had been reading SB on and off for three or more years and had completed Rescue by the time the idea of "shop for the instructor not for the course" really sunk in.
