Honestly, there is only one simple and pretty straightforward goal -be happy with how you did in the HSC. Do not think about anything else, and you certainly aren't a disappointment to anyone really because of one simple reason - you tried and its fine if you don't know. My friend and I were in...

Well... about the first one what you have said is correct - they are hydrogen bonds, all of them - and is also the key reason why stuff like nylon (amine group) and acrylic (CH3COOH) have the properties they do - they are strong partly because of this factor. And also boiling points which you...

Investigating science is much closer to senior science in terms of both scaling and content (i think). Science extension is extension - wasn't meant to replace senior science which some dropkicks used to do.

Okay so in terms of difficulty I would go as far as to say that a bio mark is not a good indicator of how well you will do in science extension. It is a difficult subject to get a band 6 in because the boundaries are not very clear, there is not a lot of material nor are there any reference...

Bro there's not eas points for international students its only for domestic students. Telling from experience because i am an international student who finished the hsc. I will be completely real with you - the externals is still 50% of your thing and you need to get it down to a certain extent...

So... I did science extension so I feel like you need a warning. I dropped bio btw. But what im getting at is that 1) many students have hated science extension - this im telling this because they chose the subject because they taught it was gonna scale well 2) As much as I can say that the bio...

First tho that is a really sad and lazy question because it is just a refurbished dot point in the syllabus, but other than that, the obvious would be 2 historical and 2 contemporary methods. For me, it is easily segregated in four sections: 1) Why was the speed of light measured The...

So the idea for question 15 is to identify that the reactants shouldn't be completely reacted off to create an equilibrium (as only water will be left, which is not a buffer). With this, consider the eqn: CH3COOH(aq) + OH−(aq) → CH3COO−(aq) + H2O(l) Mole ratio: 1:1 to completely react each...

ye didn't mean to annoy you. Just found it funny that you're s0 good at helping that you have had to think about "maybe im doing too much". That I found funny but I respect too. You certainly aren't stopping people as well so yeah. :) (although i didnt expect to be called out like this lol)

It doesn't make sense because the trajectory is not symmetric. Furthermore, they are sort of assuming that there is no horizontal velocity and hence, would result in an improper answer. But most of all, really, is the value of t they are using for the second part when compared to the first part...

Sometimes schoolss get more funding if there are state ranks (not 100% sure) and helps with recognition. Individually tho, it is basically what @laterz laterz said

I think it is possible. Although sometimes things might not be the way you want it be, it might not happen but you are in a position to try for it.

If you're looking for a syllabus prescribed move for Mod A, Billy Elliot isnt too bad.

Calm down. English in the HSC is not that important, especially how it is done in school. I tell you I did not get a band 6 in english and im pretty sure no one around me believes im dogshit at life or im messing up my future because of it. Even my own English teacher told me that is a subject...

A really neat tip my English teacher told me was: 1) Try to write your answer by filling up all the lines they have given you (ofc +-2 lines) - this is enough to satisfy the hsc markers for the first 1-2 marks, from there 2) have like 1-2 quotes for marks 1, 2 and 3, 4 quotes for 4, 5 and 6 and...

True but it was a lot of litres and like 10 repetitions for each trial. A bit much my school.. low rank and just got a new building so they are like low on money.

My bad. I didn't mean sodium nitrate. I needed calcium nitrate. And I used about 15 L over 5 months.

yep agreed. I had to basically annoy the head teacher for 3 months straight to buy me enough calcium nitrate... and I ended up using up all of the lab's supply plus half of their entire budget. So... yea - i mean in some ways if there are very few students your report doesn't even matter - only...

Bro that's what science extension is for - best subject in the HSC for me - given it is done properly. You can do any experiment you want and you can go into how much ever detail you want (like 3rd - 4th year level, some people even published their science extension papers in a journal). It is...

Oh a 1000 - yep misread the question.
