i 'll give you a clue- 90th percentile means you performed equal to or greater then 90% of people in a particular course
Post a list of questions and we'll answer them.
Please don't just ask us to explain everything... it happens too often and we tire of it very easily. Complete explanations are available in many past posts (there's a search function available for these forums too).
But if you have specific questions, they can be answered easily enough.

Some questions:
1. You know how our HSC marks are rounded up. Do they use the
original mark (e.g. 83.5) or the rounded up one (e.g. 84) when calculating our uais?
2. Does the gap between each students' school assessment mark determine how our HSC exam marks will be allocated as our moderated assessment mark?
3. When will the new version of laz seeker come out?
thnx

1. They dont use ur reported HSC marks to calculate the UAI - they used scaled marks which noone except UAC knowsOriginally posted by blah

2. yes, the gap's are generally preserved
3. stay tuned to the BoS site

Can you explain how the scaling thing with individual schools work?
Say one subject at a school has a big gap between the highest and lowest mark (90% - 50%) does that affect scaling??

Scaling is done on exam marks.
Moderating is done on assessment marks.
They are both completely independent of each other. Gaps in marks at a school will not affect the scaling of the exam marks at that school, but it will (logically) affect the moderating of the assessment marks at that school.

ok...so moderation affects your internal mark, which contributes to the final HSC mark
how do they calculate the internal mark (forget scaling, moderating...whatever, just the raw mark)
Do they work out each assessment mark according to the percentage its worth then add it all together?
Say I did four assessments for english:
weighting mark
20% 10/15
40% 25/30
20% 16/20
20% 7/10
what would be my internal assessment mark for english?
do I just work out the percentage and add them all together then divide by 2 (cause internal assessments make up 50% of final mark)
I worked out 38.3/50 (which is like a band 4!)
Is it something really complicated? Cause it seems impossible to get in band 6

Yes.
Your weighted mark for each component would be:
20 * 10/15 = 13.33
40 * 25/30 = 33.33
20 * 16/20 = 16.00
20 * 7/10 = 14.00
Total = 76.67%
which is equivalent to your 38.3/50.
No - don't do this. There is no dividing by two. Your assessment mark for all 2u courses will be out of 100. It is true that, once everything is finalised, your moderated assessment mark will be averaged with your aligned exam mark to give your HSC mark, but you shouldn't simply halve your assessment marks before this time. Don't use that excuse to trivialise assessments.
It would be very difficult, if it were all based on raw marks, as you are implying. But it's not. All the marks are moderated according to the performance bands, and hence the raw marks don't have any meaning at all (in terms of bands).
In a certain ideal situation..
Could a raw assessment mark of for example 3, be scaled up to no end - ie. if you were top of your school (the others received 2s and 1s) and received 100 in the HSC exam..?
I assume the answer is yes and sorry for taking it to the extreme - but I am just checking
