Are you familiar with the IANTD material?
I've been following this thread with interest, though I thought it had died. Nitrox is one subject that could be reasonably learned with private study, though there are some aspects that are best talked through face-to-face and of course there needs to be an interactive examination session to be sure you don't just know the material but understand it.
I'd say you may well know the subject very well, but you haven't been subjected to any verifiable objective test of that knowledge. So I'd like to see you complete one of the "recognised" agencies' nitrox exams.
