Title: ATAR CALCULATORS
Post by: kevinboy328 on October 31, 2016, 06:04:00 pm
I know that they aren't the most accurate but still, would you insert your raw or alligned HSC mark into the matrix/profiency atar calculators?

ATAR Calculators work from aligned marks, so you'd have to estimate your aligned mark and pop that in for the best picture :)

Are aligned marks like scaled marks?

Scaling happens with aligned marks as well, but it's normally a term that's just used everywhere! By aligned marks I mean the marks after Band cut-offs, option alignment, school assessment mark moderation, etc etc, the mark on your HSC itself! :) (scaling happens AFTER that) :)

ohh ok
do you know what the difference is between the scaled mark and the atar equivalent (from talent100's atar calculator)?

Scaled mark is the mark that comes out of the scaling algorithms (your HSC marks go in, scaled marks come out). Most of them scale down because that's just the way the algorithm works. My understanding of the ATAR equivalent is that it is just an approximation of your ATAR at a subject-by-subject level. It doesn't have grounding in the actual process of determining your ATAR. I think Talent 100 is just going, if you got this mark, we'd expect this mark to be attained by a student having an ATAR XX.XX. Or it could be some kind of average, I'm not sure :)

Yeah the calculation for ATAR is a pretty obscure process so I wouldn't focus on scaling too much, just know that it happens. ATAR calculators gives a good generalisation on your potential ATAR but when you use them, don't take a "this is my atar" attitude. There is a potential for it to round higher or lower than the ATAR you get so it can mess with you emotionally so be prepared for that if you are going to use it :)

Definitely agree with this! My ATAR was underestimated by about a point, which was pretty accurate to be fair, but others got ones many points higher or lower than estimated. Take these with a grain of salt ;)

In a nutshell, the ONLY time you should be touching the ATAR calculator is the day of HSC results release. Only THOSE marks have undergone alignment.

And even then you still risk inaccuracy. But that's the only time where this inaccuracy has been minimised. Because not even extensive analysis with the raw marks database is sufficient as that's historical data.

All the technicalities have been established above.

I honestly wouldn't rely on them at all. I had some friends that had an estimated atar which was 9 points above their actual atar... so they got pretty disappointed. I had other friends whom got an atar of 5 marks higher than estimated :P :D haha. Usually atar calculators after you get your marks back from the exam are pretty accurate though :P My cousin checked about 4/5 last year and got within 1+- away from her actual atar.

Ehh, I touched them all year (with knowledge that I was estimating my estimate, so the real thing was going to swing by 5-10 points), soz ;)

Who was the one that said to ignore weird things like school ranks altogether :P

At least I reckon everyone touches them despite warnings haha, just yeah need that knowledge behind it.

Well school ranks don't influence the scaling/alignment algorithms, that's why I say to ignore them. But provided you know the inaccuracies involved, I think it's only natural to want to estimate where you sit! For me it prevents unfounded disappointment, or equally, unfounded optimism. I suppose I'm for optimistic realism ;)

Wait so what actually is the aligned mark? Is it just your raw mark moderated to how everyone else goes? And if so, does it normally go up or down haha

Essentially yeah! The aligned mark compensates for difficult exams, different options, exams that aren't marked out of 100 (etc etc), it almost always goes up from what your raw mark was! Check out this page for more info :)

You have a raw examination mark out of 100 like you would in a school exam. Then judge markers determine the band cutoffs between a 5-6,4-5 etc. For example, lets say the raw mark cutoff for a band 6 in a certain subject is 82. If i score a raw mark of 82/100, my examination mark for the HSC will become 90( the band 6 cutoff). Lets say u score slightly higher or lower of the band 6 cutoff, ur examination mark will be slightly above or below 90. This work again for every band cutoff and ur mark gets ajusted to what these raw mark cutoffs are. Once this is done, u have you internal assesment mark and you external HSC exam mark which together get averaged to produce a HSC Mark. This is what you put into ATAR Calculators.

Remember also that your internal marks are moderated to reflect the performance of your cohort! That's the tricky bit to estimate :)

Hahaha yeah I agree with you- I remember being so worried and stressing about the complicated ATAR calculation system back when I did my HSC. Best thing I found was to just go into the HSC with the "do your best attitude". Its cheesy I know but that's all anyone can ask of you. You can vanquish HSC!! :)

Bump? I want to know what an aligned mark is.
A mark that has undergone alignment is the one that's reported on your HSC certificate. All marks need to undergo alignment to cater for the fact that in some years the course is harder than in other years (notably, the final exam).

The raw marks database displays the raw marks students achieved in the exam, alongside the mark post alignment. Note that these raw marks need to be bought.

A team of 'judges' decide on the alignment algorithms every year.

Yea, true. ATAR calculators don't really change anything for your actual ATAR, it is just a good thing to "know".

Would you say putting in your year 11 marks are a fairly
accurate representation of what you are going to receive for your atar.
I was pretty slack in year 11 studying like i did in junior years (basically writing
my notes the night before and didn't touch practice papers)

i put my year 11 marks in and got an atar of 82 ish but aiming for +90
I've definitely changed my mindset for year 12 and have been
doing much more work and practice papers.

Do year 11 results show a reflection of your ATAR or are they irrelevant?
advice?

In my opinion, Year 11 results should do nothing more than indicate subjects where more work is needed.

Especially in your case, they clearly don't represent the work you are going to put in this year. For that reason, your Year 11 results won't be reflected in your ATAR, provided you are working hard to improve them ;D

Also keep in mind that Year 11 results aren't included in calculating your HSC results in any way, shape or form. :)

katnisschung, that is a very good question, but that depends on if all the same factors are the same.

If effort, family environment, etc are all the same maybe.... But rarely are things the same.

Since you were pretty slack in year 11 towards study, I'd say it is not representative.  Just write your  year 11 mark off.
*Year 11 marks do not contribute towards your atar at all*
