Is unit 3/4 chemistry harder than unit 1/2 and how much by?
Also to get a study score of 35 how much would i need go be averaging in my sacs? In unit 1 my average for tests was 78% and unit 2 it was 60% and on both mid and end of year exams i got 58%. Do i need to work harder?

To answer your question on what you'd need for a SS of 35. A very high B+ on the exam would get slightly over 35 given you have a decent sac rank this varied in 2013 & 2014 from roughly 89-94/120.

Hey Sine,
Do you know what sort of scores, what I be required to maintain in unit 3/4 chemistry for a 49-50?
-
From what others have got in recent years 114/120 has ranged between a 48-50 with full scaling sacs.
But last year was apparently very easy resulting 115/120 getting a 48.
So 49-50 range would be anywhere between half to a single mark from that.

I got 57% on my end of year exam for unit 1/2 chemistry but I understood all the concepts well. What my teacher recommended and I started doing was plenty of exam type questions (The one he gave us was challenging but I made silly mistakes dropping 23 points in the short answer, shocker :'(). IMO if you got 58% and understood the concepts/calculations in unit 1/2 then unit 3/4 won't be as hard for you as it would be for someone with no previous experience with chem. As for the study score I'm not to sure what would be required for a 35 but I think it you would require C-B+ on SACs and an above average exam score, so above 60%. This is just based off the fact that 30 seems to be the average SS for a lot of subjects. Anyone can correct me if I'm wrong :)

Firstly - yes, 30 is the average for all subjects.
But remember that study scores aren't linear, they're a bell curve. A score of 45 puts you in the top 2%, but 40 puts you in the top 8%, not 4%. With this in mind, for a 35 (which is just after a very thick part of the bell curve), you're probably looking at scores more like 70-80%
You'll also need to compare to grade distributions to figure out how many people are getting an A, B, C, etc. For some subjects, 80% is the average score, but for others it might be 55%.
Tl;dr, the system is complicated. The easiest way to get the score you want is to aim to ace everything. ;)

To answer you question as to whether chemistry 3/4 is harder than 1/2, I will say only slightly more difficult as you will be building upon what you have learned in 1/2. Hence it will be really helpful if you have a solid foundation built from 1/2 in order to proceed smoothly to 3/4.
The essential topics that I highly recommend brushing up are:
- Stoichiometry, including molar and volumetric calculations
- Acid Base reactions
- Redox reactions
The rest are pretty helpful if you understood them. To do better, definitely try to understand chemistry and do ample exercises.

you really want that 99.95 don't you ;)

My chem teacher always says that 3/4 is easier than 1/2, simply because of the fact that 3/4 chemistry mainly expands on your knowledge of 1/2. In 1/2 you learn new concepts for the first time, which is always the hardest part. But in 3/4, you are simply expanding your understanding of things you already have basic knowledge about.
In this regard I'd say 3/4 is easier than 1/2. :)

I wouldn't exactly agree with that. If you have a look at the VCE chemistry curriculum, it states different topics for each curriculum. However, they might go over the topics, you learnt in units 1 + 2 in a glimpse in year 12.
Here is the copy of the curriculum :)

You're missing the point here - AceVCE777 is correct. Some topics are different, yes, but other topics are built on top of 1/2 knowledge. For example, you study organic chemistry in 1/2 and then expand on that knowledge in 3/4 with some extra material. Same goes with acids and bases, you study them in 1/2 and then you expand on it a bit in 3/4, for example calculating the pH of weak acids, which is new because you only calculate the pH of strong acids in 1/2
-
Fun fact: everyone teaches 1/2 chemistry differently. If your teacher tells you something, it's probably true for your school. If someone else's teacher tells them something, it's probably true for their school.

Is unit 3/4 chemistry harder than unit 1/2 and how much by?
I found 3/4 chem harder than 1/2. In 1/2 chem, there's more of a focus on calculation questions rather than theory and I found that easier to grasp. (Probably because I'm more maths orientated)
In 3/4, I found there to be more theory/memorising which to me, was harder.
However, depending on your strengths, you may find 3/4 chem easier since you're reinforcing your 1/2 chem knowledge whilst learning some new concepts (which is mostly theory).

yes, but I meant to say was that it isn't directly expanding from 1/2 chemistry, unlike maths where one would learn something in units 1/2, and would further expand/use those skills in units 3/4.

It is - some aspects of 3/4 chemistry are directly expanding on aspects of 1/2 chem e.g organic chemistry and acids/bases
-
well yes, the scope of knowledge in Chem 3/4 is quite broad (and is quite different from 1/2), and the amount of awareness/care for 'special cases' is quite high. For that reason, in my opinion, Chemistry is probably harder than subjects like Methods/Specialist.
But of course, Chem is definitely doable.

My teacher absolutely could not stress this enough during year 11 orientation and year 12 orientation. I guess this means it's true :)

Another fun fact: Always read the posts below you before replying haha. This should also be taken into account and also how people learn and understand the concepts that their teachers teach them i.e. hands on like with the building of 3D hydrocarbons or through reading and hearing

I am honestly confused as to how what you've said has anything to do with what I wrote?

After commenting I saw your post which should've been taken into account as well as what I agreed on in the above post. Straigth after posting I saw you "teachers teach differently" comment and was like "wow, should've read all the posts before giving my two cents" hence the "Another fun fact". Never mind :-\

At first I thought you were having a go at his 'fun facts'- and then I thought 'how do you read posts below you before replying like I can't see the future'--->I think these holidays/reading too many sassy memes/PVTSD are making me senile :) Now ^ makes sense :P

What if my teacher makes the sacs really hard and the average is like 60% would i need to get around 70-80% still to get a 35 study score?

It could do, definitely. Just remember that SAC scores scale to the exam - your best bet is to be in the top half-top quarter of SACs and do well on the exam (can't say for sure without looking at the grade distributions - let's say around 70-80%?)

Ahkay, I getcha. See, I thought you were having a go at my fun fact, so.
