Just want to say that I bloody love this website even though I feel like a psycho every time I use the archives.
I am totally with you.
Scaling reports have some errors
43 methods 2015 scaled up to 47.6 not 47.4:)
The scaling report there is just a guide. The scaled scores for raw scores of 40, 45, and 50 are straight from the VCAA scaling report, and everything else is an estimate, but even the ones in the VCAA scaling report are rounded to the nearest integer.
The scaled scores for everything that's not 40, 45, or 50 that are shown here look like they are calculated by linear interpolation i.e. under the assumption that the scaled score increases by some fixed amount every time the raw score goes up by one (with a possibly change when you hit 45 raw).
Would be very difficult to list all the numbers for all these subjects correctly, because the only way to do that is to find a person who finished VCE this year for each raw score within each subject. Actually, that's probably something AN could achieve with some of the more popular subjects.
