Thanks for replies... I'll give you the background of my nitrox course. I originally had my aow course booked in. I enquirer about what to do after and the owner of the lds told me to do my nitrox, which he said was only another $99 on top of my course. I paid the extra amount and I was handed a thin quite thin book from padi. I was going to go to the night course but I work shift work so I arranged to come in by the shop and run through a few things. I was given a multiple choice exam, it was graded then and there I analysed two bottles of nitrox. End of story. Knowing I want to progress further I have done my own research and hence the questions.
Being in the emergency services I have a bit of an idea of twa (total weighed averaged) and short term exposure limits in regards to chemical exposures, so if I can get some decent info I should be right to wrap my head around it.

Oh no disrespect to the shop owner in that comment he has been very helpful in other aspects and accommodating, I just feel that it was a gimme getting that cert and it could have been taught a lot better
