although Laz is probably constructing a nice explanation for you at this very moment, remember that HSC marks are usually much higher than raw assessment marks. Many schools like to set their assessments harder so that in the grand scheme of things, marks for their candidature can be scaled up for the "moderated assessment mark" component of the HSC
I might add that, if the distributions of students between bands in each course are significantly different to last year's distributions, LazSeeker might not be all that accurate for 2002.
It seems that the general opinion is that the 2002 HSC exams have been easier than the 2001 HSC exams. I couldn't say for sure whether this is the case or not, but if it is, and you're trying to predict your UAI for this year (which we don't claim to be able to do), LazSeeker will likely report something that is slightly too high.
In reality, the UAI is calculated from scaled raw marks. No info is released about these raw marks, so LazSeeker cheats and skips that step, instead calculating the scaled mark directly from the aligned mark that the Board reports. The difficulty of exams and so on does not affect the actual scaling processes, but it could cause a few discrepancies with regard to LazSeeker, as it uses aligned HSC marks.
And to reiterate what Christine said... it's only an estimate anyway.
I enter in 70 for all my subjects (advanced english, modern history, tourism, environmental science and business studies) and it gave me a uai in the 50's.....
Ive got no idea what marks i'll actually get....BUT i was expecting it to give me a way higher uai estimation
Considering that the average marks for those courses were 77.4, 74.4, 67.4, 73 and 73.8, and the average UAI is ~66, it's not entirely surprising that you're given a below average UAI when you enter below average marks.
Mmm I don't mind yes/no responses, but I really don't have the time (esp. now when I'm meant to be studying heh) to sit around trying to calculate values. especially when there's documentation and programs out there that can help you.
