I checked into this option for my wife as sometimes she lioves diving and other times not so much. I figured she could do her aow slowly. It can be done by doing five separate specialties, but it will require more dives. In aow course you do one dive per specialty, but if doing it separately, each specialty is 2 or 3 dives, but you can combine nitrox along with another, killing two birds with one stone. This is because the nitrox course can technically be completed without diving as it is all pre diveI wasn't aware of that... it seems a little bit "un-PADI-like"? So a student could do 5x 'adventure dives'... not requiring a manual? And then be qualified to apply directly to PADI for AOW certification? Doesn't sound right...?
