Not including Section IV hard to tell, because I've studied the accounting stream which means I'm not sure what the limit is on accounting in the other two streams, saying that I've heard that Petty Cash/Simple General Journals/Depreciation worksheets/Bank Recons are the norm that all streams do. There might be an additional one I've missed, but yeah, those for sure(especially since 3 of them were in the trial, I definitely think one or two will reappear in the HSC). Anything they do put for accounting though is generally a shortened version so don't worry too much.
for accounting stream I reckon Subsidiaries/Financial Statements/Balance day adjustments are a good possibility,the annoying part of it is the 4-10 marker where you need to describe the process behind it,it really should just be pure accounting
(i hope they make it so on this paper!!). If it gets annoying,I'm even thinking of doing another stream just cause when i look at the trial questions, i can probably answer them to a near 18-19/20.
