As in do you submit your raw marks or your aligned HSC marks?
Okay, so the calculator works off aligned marks but the actual ATAR calculation is from raw marks?ATAR calculators work off aligned marks. They are then scaled (through the ATAR calculator) to obtain an aggregate score out of 500 (which adds up the best 10 units worth of scaled marks) and this then translates into an ATAR. Hope this helps.
No, the actual ATAR is also calculated from aligned marks, i.e. very hard to predict this from your school raw marks and even your practice hsc marks for that matter - so even the ATAR calculator is going to struggle to predict your ATAR.Okay, so the calculator works off aligned marks but the actual ATAR calculation is from raw marks?
I thought that BOS gives UAC the raw marks and then they scale them, so the scaled marks are different to the aligned marks.No, the actual ATAR is also calculated from aligned marks, i.e. very hard to predict this from your school raw marks and even your practice hsc marks for that matter - so even the ATAR calculator is going to struggle to predict your ATAR.
Okay, THIS makes sense. That's why I was confused, because I read on the BOS and UAC sites that BOS gives UAC your raw marks and then they scale them. If the scaled marks turn out similarly to aligned marks I can understand it now. Thanks!UAC uses your raw marks and your moderated assessment marks from the BOS and then applies their own scaling system. They don't use the aligned exam marks which BOS gives.

So really, the AtarCalculator doesn't actually use the right method of calculating an estimated ATAR, but because the UAC system of aggregating is close to the BOS aligning system, the marks which they use are similar to the BOS aligned marks, hence why ATAR estimates are fairly close.
