This is not biology related but
Usually when I download a file it would appear at the bottom of my screen the download status bar and I have no idea why it is suddenly not appearing why my downloads are not showing up on chrome

If anyone knows how to fix this

HSC Mathematics Advanced / Re: Mathematics Question Thread
« Last post by FlammaZ on 14 minutes ago »
Because i am new i dont really know how to use the site yet i just click on reply, sorry about that, this might not be the right area to post that kind of question. However what i am asking is this: why is it that (refer to question 4)- you must find the area under the curve, to get the liters , i thought you just had to integrate the dv/dt, which would give you v(t), then just find v(5). 

What i am trying to say is, once you integrate dv/dt, you get v(t), v representing the amount of water in the tank, and t the time in minutes. Now, number 4 is asking when t=5, what is the amount in the tank, it seems simple to just sub 5 into the equation and get the amount. Why do you have to find the area under the curve instead ?

Hi everyone, I just need some advice on what exams I should do for chemistry.

I want to save the 2016-2019 (NHT incl) VCAA exams for a bit later on, closer to the exams. I know that VCAA is the best resource for doing exam revision, but I have done SO many checkpoints questions/past exam questions through the year - and especially some of the trickier VCAA ones, I actually can recalll the answers to them when I see them. I tried doing the 2013 VCAA paper today, and I had pretty much done most of the questions before/they aren't on the study design. This left very few questions left.

Am I better off going through the entire papers again so I can 'add that exam to the list of exams I've done,' or just choose the questions I know I haven't seen before?

Also, how worth it is it going through much older VCAA chemistry exams? Has there been a lot of changes since then?

I have access to many company exams, but I do know that they're not the adequate preparation.
I feel lost and stuck and I'm unsure how to revise.

I very much regret doing so many exam questions before my SACs. :(

Would love some advice :)

HSC Subjects + Help / Anki
« Last post by N2003 on 1 hour ago »
I am in year 12, I started using Anki, and it has been very helpful however for certain subjects there is not a lot of time and a lot of content to go through, I was wondering if anyone has Anki cards for the following subjects, Chemistry, Physics, Mathematics (Advanced).??
TY very much in advance.

One of my friends friend got a second round offer on the 20th.

If one was to receive a derived exam score, will a medical certificate be sufficient for an approval (personal reason)? Also, has anyone had experience with derived scores, were they happy with their derived study score?
What is the process? Does the student need to sit the exam and then appeal or do they appeal before the exam?
I read a atarnotes forum from 2011 and it said that they mainly use the GAT and sacs, do they still consider these?

does anyone here know a good way of remembering/ explaining 3' and 5' strands like i relearned it a hundred times but i keep mixing them up. which way is downstream? do i even need to know?

anyone got second round offers yet?

Before I answer this question, I feel it's worth quickly explaining how an ATAR is calculated:

Basically, at the end of year 12, your SACs and exam marks are combined to produce a "raw study score". Based on if that subject was perceived to be "harder" or "easier" (based on objectively comparing how highly people scored in that subject vs. other subjects they did), it will scale up or down. You may already be aware of this, hence the nature of your question. The way the ATAR is calculated is by adding those scaled scores together to get what's called an "aggregate", and then everybody is ordered by that aggregate to get an ATAR based on what percentile you lie in. (eg, if your aggregate is in the top 5% of aggregates, you'll get an ATAR of >=95.00) This means that what scores will get you what ATAR will vary by year - this is important, because it means nobody can ever *truly* predict your scores. Which sucks, but it is what it is.

So, does scaling affect what aggregate you can get? Well, last year, if you got 6 scaled study scores of 50 (the supposed "highest" study score you can get), you got an ATAR of 99.90. Yeah, not even the highest ATAR. This is because some subjects scale higher than 50 - usually languages and specialist maths. So if you're aiming for a 99.95, you HAVE to have a subject that scales over 50, however if you only want a 99.90, you can get a 99.90 with subjects that don't scale over 50. You're asking for a 98 - to which I have to say is yes: mathematically speaking, you 100% can get an ATAR of 98 even with subjects that don't scale up. But will not having scaling subjects make it more difficult?

I direct you to the scaling report. The way to read this is that the top numbers are your raw score, and the ones next to the subject are the scaled scores. You might notice scaling isn't a flat increase - eg, if you got a 25 in chemistry in 2019, it increased by 3 - and if you got a 30, it increased by 4. The most important part here is that scaling is largest the closest your score is to 30, and smallest the further away you move. This is by design. In fact, by the time you hit 45, most of these scaled scores have moved by 1 or 2 AT MOST. To get an ATAR of 98+ last year, you had to get scaled study scores of ~44 in all your subjects. Not an easy feat, sure - but the take home here is that even if you had subjects there were scaling up, they're not going to scale up by that much at all once you're scoring that high, and subjects that go down aren't going to change by much /either/. So no, I would say that scaling won't affect your chances much at all - it will be slightly harder without subjects that scale up, sure, but you will always score highest in subjects that you enjoy and are good at, so if you need to score that high anyway, it's worth sticking with those subjects that you know you'll get a good score in, instead of trying to rely on scaling to fix your ATAR for you.

EDIT: Beaten by Sine by a lot lmao, but I put in the technical details, so I'm leaving this here.
