hey courtz,
i guess you just need to study the whole course - take a look at the syllabus - there's a lot of info in the hosp syllabus that isn't useful but if you look at the right hand column i think that should give u a good indication of what to learn...
try revising prac papers - i find it easier to make acronyms for things like the HACCP plan etc.. just read over you info, make summaries and i'm sure u'll be fine.. although a major hint our teacher gave us was to look at the news and 'update your hospitality knowledge' as that's one of the units... like world events e.g. Sars, 9/11, collapse of ansett, bali bombings...and how they have impacted on the tourism/hospitality of australia.. write some prac responses and include that info... it shows the marker u actually know what ur talking about..
hope that's helped! and goodluck!!
