Understanding and drawing Galvanic cells

Hello, Year 12 WACE ATAR chemistry student here. I was wondering if anyone could explain the Galvanic and Voltaic cell exam questions to me (specifically, but not limited to, how to determine what is an electrolyte, and how to draw a full mark cell diagram from a description)

I have an example (attached below), and I'm not sure exactly how to explain it, even after consulting my teacher and ChatGPT; I just thought someone might have another angle here.

Also, I would like to know whether they can get any harder than this (I assume they can—like not giving the Half-cell equations), and if so, could someone provide an example?

Note: A random example claude made up for me (apologies for not having a proper exam question on hand)

Note: Apologies if this is not what this community is for (I see a lot more posts about overall concerns, so I don't know if this kinda of question is permitted)

What scores should I be aiming for to get 85+ Atar (Also Tips for methods + chem)

Hey y'all, year 12 here doing Methods, Chemistry, Human Biology, Psychology, and English for ATAR. Currently, I'm really stressed (as I'm sure most are atm) about whether or not I'll get into the course I want to at Uni with my current results (engineering). Last year my school told me my projected ATAR was 94 with the following scores:

  • Mathematics Methods: 68% (only one test has been marked) -- 75% for the final exam.
  • English: 68%
  • Chemistry: 63%
  • Psychology: 81%
  • Human biology: 65%

Note: I'm not sure how accurate the 94 was, considering how low these scores are.

Year 12 has been pretty rough for me, even though Im still trying hard, so currently my results are looking as follows:

  • Mathematics Methods: 48% (only one test has been marked)
  • English: 63%
  • Chemistry: 60%
  • Psychology: 74%
  • Human biology: 61%

I know these scores aren't great, to be fair, especially methods, so I know I'll need to get a grip on that as soon as possible, but what kind of ballpark should I be aiming for if I want to be getting into engineering?

I would also like to ask for advice on how to improve my methods and Chemistry, because it's really frustrating that I'm not doing well despite putting in so much effort. The people in my year are really good at methods and chem, so I'm not sure if I'm just stupid or am missing something, but I seriously don't know how to improve, considering I have tried doing practice exams, tests, and worksheets for hours and still ended up failing.

Transition from year 11 to year 12

Hello, Year 12 here. It's been a while since I posted on here. Year 11 was going well for a while, and I got a projected ATAR of 94. My previous years' ending percentage grades were as follows:

  • Mathematics Methods: 68% (only one test has been marked) -- 75% for the final exam.
  • English: 68%
  • Chemistry: 63%
  • Psychology: 81%
  • Human biology: 65%

My current Grades are as follows:

  • Mathematics Methods: 48% (only one test has been marked)
  • English: 63%
  • Chemistry: 60%
  • Psychology: 74%
  • Human biology: 61%

But now I'm back to what feels like square one in year 12. I have been getting horrible grades, even for ATAR, and have been consistently getting below average. In fact, I failed a maths test (on calculus) for the first time ever, and just today, I found out I failed my acid-base chem test. So to be honest, my motivation is really being tested right now. I study really hard, do all the practice exams and tests I can get my hands on, and then, on the test, I just blank out or simply don't explain it exactly as the marking states, so I lose a lot of marks. I have exams coming up, and I don't really know what I'm going to do, because to be honest, it feels like whatever I do, I end up getting crushed either by anxiety or the marking key.

Anyone who has already graduated or is in year 12, can you share some tips on how to improve on this? I honestly don't know how I've been screwing up so badly over the last year, especially since I want to get into engineering. I don't want to give up yet, but I'm really not sure where to go from here because, as I said before, I feel as though I just don't answer the 'ATAR way' even when I study the key SCASA terms, costing me marks, even though I understand the content.
