2 unit might increase though seeing that how poor the scaling was generally (even 98 aligned = 94-95 scaled mark wth)

Ah how is it the maximum scaled set of marks? Doesn't the cohort generally vary from year to year, thus affecting scaling?

Download Adobe Acrobat here or get the latest version:

Adobe - Adobe Reader download - All versions

Hope that helps.

Edit: Sorry about double post.

I already have Adobe. Are the Tables opening for you?

If you wish that the scaling for MX2 increases for 2009 you had better wish that the cohort for it is intrinsically better than the cohort for 2008.

That means... all the dumbassess out there who are doing MX2 (no offense) - killemall.

Yep you are right.

However, from what I see, 2008 has the best scaling for maths in the past 10 years or so. I doubt it will just suddenly happen again.

Foxit Software

Foxit> Adobe

Adobe is shit.

[dp624]

Actually to be honest I don't like Foxit mainly cos its print system sucks.
If you have a decently fast computer then Adobe Reader is better (it has a background program that speeds loading)

But if you only want to read the pdf Foxit is definitely better.

Back on topic: So the scaling figures for this year don't really affect us 09ers?

[dp624]

Not at all. it's only your cohort that affects you.
Now, if you are incredibly mean go and kill those people who you don't consider 'worthy' of the course, as they'd lower the scaled mean, which in turns lowers scaling

lol, 1000th official post =P (oops not 100 lawl)

edit: 1000th post..

And yep, "dumbasses" do lower the scaling of the subject but meh, most people who do 4 unit are quite decent.

I've put something together in Excel to show the factor that the HSC marks were scaled by, for those who are interested. I've also made it so that you can compare two subjects' scaled factors by drop down boxes.

I haven't done this before so, I'm not sure if this way shows anything much or if it's useful, so any suggestions on improving it would be appreciated.

Yes, it is difficult for the scaled mean to go any higher. While the scaled mean of 44.5 in 2008 isn't the highest ever scaled mean, it is certainly one of the highest.

It means that, on average, the 3089 students who took the course averaged a scaled mark of 44.5/50 in Extension 1. There would need to be a very large difference between the performance of Extension 1 and Extension 2 students on the Extension 1 paper for the mean for Extension 2 to go any higher.

So what does the P90, P75 stuff stand for?

This could help for a comparison of Maths ext 2 scaling between 2007 and 2008.

oh wow those are some amazing stats haha. I guess it's a bit harder to get a UAI of 99 or above without 4u.
I think the effort/scaled marks ratio for that is one of the best =P

Px is the xth percentile. like, the 99th percentile got, say, 98
