In uni it's great if you can get high marks as like HSC receiving a good result is rewarding. The marks would be particularly important in some scenarios such as those wanting to do any further studies like a masters or PhD, were the main assessment on if you gain entry is based on how you...

If something is missing from the answer then it's not possible to get 7/7 or full marks for it. However, 3/7 for one thing left out doesn't really seem like a holistic way to mark. I doubt in HSC they are going to just destroy the response for something like that. It will probably end up getting...

It's not weighted so it won't impact ranks but it's still not really a smart idea in my opinion for other reasons. Trials is the first time most students do a 3 hr exam in timed conditions and the feedback here in how you answer questions is important. If you are writing what your friends know...

I've had messages like that from people randomly out of the blue as well before asking to do their quiz or help with exam questions, not for HSC but at uni, but it's still the same kind of thing in terms of someone asking you to do something that they should be doing. It can be awkward saying no...

You can pick a major after a year, but you need to have some idea of what subjects might be necessary for it. As often in the first year you need to complete certain courses for that major, like for instance things in the biology degrees probably have similar first year courses, but that would...

I did accelerated 2U math as I did HSC for it in Year 11. I had the option to take 4U based on the 2U mark, but decided against it because I knew I was going into a science degree and therefore wanted to focus more on the chemistry and physics subjects. I did do 3U math though, I would say I...

The stuff learnt in HSC Chemistry probably isn't that relevant to mechanical engineering (know from a friend of mine doing the degree). If there was any small amount of knowledge necessary I doubt it will be assumed and they would teach it at uni, the person doing HSC chem won't really get any...

$80 per hour in my opinion is too high if the tutor has just graduated, as even if they say something like 'I freshly just completed the syllabus and I am up to date', isn't more beneficial than a tutor who has taught the content multiple times and has experience in how to teach. As tutoring...

First off going tutoring doesn't necessarily mean you will get amazing marks. This can be seen in the high number of people going tutoring and the low number of people getting 99 ATAR, so it isn't pay to win. Students and parents often think that going to a tutor who achieved a high mark will...

You should either learn the ext 1 math material yourself (possibly in holidays between HSC and Uni starting) or do the bridging course (ideally a combination of both so you are ready for the course). Just keep in mind though if you try self-learn some of it, that not all of the maths ext 1...

If you want to do anything related to a commerce, finance, economics degree at uni, business studies is not going to be helpful for this. The subject is basically like a you memorise all the content and you do well and as such it is easier to get a good mark compared to economics, but it scales...

Somewhere around 97 is usually the start of the state ranks (top 20) for chemistry. So getting a 95 plus is essentially like almost getting the state rank so there is probably not that many people. Can't really compare a 90 band 6 vs 95 band 6, because of the way the HSC mark is determined. As...

1) Using word substitutes isn't correct here as it's an addition reaction. The HCl is added across the double bond. There's only 1 product because if it you add Cl to carbon 2 or carbon 3, it doesn't matter as the final product will still be 2-chlorobutane if you name it using IUPAC rules. 2)...

Having slumps in studying is relatively normal for most people, but you need to have some strategies to keep working even when you don't feel like it to make sure you still keep progressing and improving. This is just the sad reality, when even you don't feel the best you have to somehow find a...

0.018 absorbance is 1.2 ppm This is the diluted solution, undiluted is 10x as concentrated as it says diluted by a factor of 10 so [Ca2+] undiluted = 12 ppm Whenever the question is to do with precipitation and it doesn't look there is a direct answer, it is probably to do with Ksp...

The priority isn't based on the type of halogen atom. It is about the total sum of the numbers used in the naming being the lowest So for example in naming this: We would either name it as: 1,1-dichloro-3-fluoropropane or 3,3-dichloro-1-fluoropropane The Cl comes first in the name as it...

Use RICE table Ag2CO3(s) < -- > 2Ag+(aq) + CO3 2-(aq) Ksp = [Ag+]^2 [CO3 2-] Ag2CO3 Ag+ CO32- R 1 2 1 I / 0 0 C / +2x +x E / 2x x Sub the 2x and x gives the Ksp = (2x)^2 (x) = 4x^3

It's like doing a molar ratio like you would with a normal equation. The equation for polymer formation is: 5 galic acid ---> tannic acid + 4H2O so from part (a) if it is known: n(gallic acid) = 0.0001092 mol n(tannic acid) = 1/5 n(gallic acid) using a molar ratio for that equation

Oxidation is one type of redox reaction (a reaction in which electrons are transferred). Reduction is another type of redox reaction. In oxidation electrons are lost and in reduction electrons are gained. These two reactions happen together normally and don't occur by themselves. For...

Doing a question a little out of the ordinary the first things to always do is do what you would do if the question was worded as a simpler example. For instance, for this question the more standard questions are: given 25.0 mL of 0.01 M NaOH is added to 100 mL of 0.02 M HCl, find the resulting...
