why don't you look at the board of studies website on it there is the syllabus which outlines what you need to know for geog, it doesn't actually include having to do any surveys, but it would be good just to 'drop' into your final essays, i do the hsc full time, and the requirements are that we have to do X amount of fieldwork hours, so we do them as a class, which is good because we know what to look for the teacher is there helping us. For urban dynamics we looked at a small town near the school, we havent yet done the tourism fieldwork - which we will be visiting a local resort for information (as a class again), so i suppose that it is actually a good thing in doing the hsc at a school is that we have to do the fieldwork as a class!! full time isnt that bad ....... you just need to have time management skills
