hahaha sorry, IT and scaling don't mix well.
It scales poorly, however your HSC mark is totally dependent on your exam mark. So if you're confident in the exam oyu can pull off a band 6, otherwise Band 5s are fairly common outcomes.
There was a change in syllabus between last year and this year. Thus there was a change in the exam content potentially making it seem more difficult. I didn't do the IT course in '07 so I can't say which course is/was harder.
There is always some ambiguous question about USBs in the iT papers...
This year I thought the question was straight forward. It was simply an Indetnify the USB port question
Last year roughly 2000 students sat the IT exam, 40 of whom received band 6s.
There are no internal marks for IT, you do not need to sit the exam and you can still get the Cert II.
Whatever you score in the exam will be your raw mark for the subject.
