CARROTSSS you are a GODSEND!! Can you please add society and culture if its not a botherrr

this calculator overestimates ur atar significantly just like any other calculator for hsc marks below 80 in english advanced.

the scaled mark (or atar equivalent) for same HSC marks should be the exact same between standard and advanced and studies.

see:

UAC compass overestimates your atar by at least 3 points for marks below 78 in English Advanced

Explanation: The UAC compass calculator is extrapolating the graph below 78 from origin (shown as the straight red line) because for some reason UAC couldn't use the whole dataset for their public calculator. However, using the knowledge that all English scale the same as stated by UAC...

this blind spot is because there’s no data below the 25th percentile for English advanced, so my model is pretty much just guessing below there.

a major update is coming soon which will address this and make major improvements to alignment and scaling modelling

yeah, it would be more accurate if you used the scaling data of english studies hsc marks between 0 to 60, standard for scaling data between 60 and 80 and advanced for 80 to 100 cause those are the values uac put in their annual report for those subjects so less guessing needed at otherwise extreme ranges for one subject

this is seriously such an impressive project, MASSIVE kudos...my only qualm is that it appears to be glazing me (ik what @coolcat6778 says about inaccuracy at low eng adv marks and I wonder, is there also inaccuracy at the higher ranges)

because no way my trial marks get me what I got (to be fair tho I did overperform significantly in 2 subjects but still)

higher ranges are fine because there is data available for those. the updated version will be using much better modelling but even then it won’t change estimates by a significant amount, your ATAR will still sit in a similar sort of range

When is the updated version coming

the modelling is almost done, we’re aiming for before hsc but no promises

wait really, i genuinely thought it was glazing me but is it fr 🥹

it won’t be glazing you as long as the marks you’re putting in are fair, the ideal use case is entering the marks you get when doing the 2022 hsc past papers under timed conditions, for which it should be almost perfect. if you do easier/harder papers your ATAR will be over/underestimated accordingly. and also if your in-school subject rankings are terrible/great then likewise

how do you account for your subject rankings in the calculator though?

 

[coolcat6778]

u don't. Just assume u will get a hsc mark same as exam mark. Assessment ranks are bs and should be scrapped. View my thread

 

[carrotsss]

more or less with vibes since it’s entirely up to your individual school.

you could get an estimate based on rankings on this forum and then your actual ATAR should be somewhere between the estimate from that and my calculator. just make a quick post here with your rankings and school’s past b6 count in each subject. this is only really accurate if you’re in the b6 range and your school gets a lot of b6s though, and if your school does much better or worse then it won’t account for that.

This gave a 99.55 atar... and i used uac later only to give me a 97.05

I wish we had smth rlly accurate and on the dot than having to estimate and do this on our own.

iirc the uac one was the most accurate for mine

UAC's ATAR Compass and this calculator are for completely different purposes, you can't compare the results from either. There's an explanation of why this is the case on the original post, but to simplify, my calculator takes raw marks and calculators like UAC take aligned marks. UAC is quite accurate for aligned marks, but aligned marks are not the mark you get in the exam, your raw marks are aligned (sometimes adding as much as 30 to your mark!) to produce the marks NESA actually gives you in December (the ones UAC ATAR Compass is designed for), and you have to pay them like $60 to get your real raw exam marks - you can see examples at https://rawmarks.info.

My ATAR calculator could still be over-estimating your ATAR though, because it's only as accurate as the marks you put in. If you're putting in your overall school assessment average, don't do that (your random presentations are not comparable to the actual HSC exam), and if you're putting in your trial marks, just keep in mind that if your trials were easier than the 2022 HSC then I can't account for that. It also can't account for if your school ranks are significantly worse/better than how you relatively do in the HSC.

The most accurate use case for my calculator is if you take the 2022 HSC past papers and mark them fairly, and then put in those marks, and if you do this, it's pretty much as accurate as an ATAR calculator of this kind possibly could be.

Other ATAR calculators are useful but for a different purpose, they are mostly designed for the period between 6am and 9am on HSC results day when you have your aligned marks but don't yet have your ATAR, or for if you estimate your results based on rankings and your school's past b6 rate in subjects, but unfortunately, pretty much none of the ATAR calculators clearly advertise this (with many spreading straight up misinformation), and honestly I think NESA is at fault for this with their highly opaque system that leaves most students/teachers confused and with major misunderstandings of the system that leads a lot of students to think they'll do much worse than they actually do.

Ohh yh now that l think about it, makes more sense, thanks!
