Mate,... (yes I'm Australian too, so pardon me if I sound a bit harsh and tell you to stop whinging and be more practical -- see below)...
I don't see anywhere in this whole thread where you have reproduced a particular problem that you had trouble with in a quiz, and asked for help solving it properly (i.e., in one of the PF homework forums). Have you done this somewhere? If so, please give links.
If you're not doing well in quizzes, it's probably because you're not actually doing enough practice quiz questions beforehand. That's the only way to find out for sure whether you understand something well.
Even at University, I had friends who thought "studying in the library" meant just reading through the course notes, but were reluctant/lazy to work through past exam questions in detail, etc. I told them to expect poor results and regrettably I was right.
So,... concrete suggestion,... if you haven't done so already, start posting specific problems in the PF homework forums, and show your attempted answers/solutions.
Even after a quiz -- if you got a question wrong you can post it in a homework forum and ask for help to find a correct answer, or even just to check an answer if you're not sure it's correct.
Oh heck, don't let that kind of nonsense stop you. E.g., University past exam papers are routinely available in their libraries. If your school won't provide them, then go around that blockade and look elsewhere. See below.DifferentialGalois said:They don't give away past papers,
Well, you can actually do rather better than that. E.g., you could:so I can only speculate what they are to give in an exam.
No, that is NOT your "best hope" -- it's the road to poor results.My best hopes currently seem to be revising the course notes and/or creating mock questions that I think could possibly appear in the given exam.

Well, you can actually do rather better than that. E.g., you could:
1) Check your textbooks to see if they have problem sets at the end of chapters, etc. Also check your library to find other textbooks on similar material. (I'm sure your librarian would help you to find parallel material.)
2) Do a bit of googling to find, e.g., "Year 8 Science Exam papers". I just tried that and found many potentially helpful resources. (Although the Australian year 8 curriculum might not match that of other countries, you could always vary the year of your search until you find something that roughly matches the material taught in class.)
I then tried a more specific google query: "Year 8 Science Exam papers Australia". The 1st hit was from kinrosscollege.wa.edu.au (Kinross College in WA). Plenty of past questions there.
My 2nd hit was qcaa.qld.edu.au, the Qld Curriculum and Assessment Authority. Again, lots of resources there.
My 3rd hit was at proprofs.com, a "Year 8 Science Exam Revision (for the Australian Curriculum)".
Further down was one from Irymple College: "Mr Hung's Science Homework".
(And there were plenty more after that.)
Summary: good, relevant practice questions are only a few clicks away via Google.
No, that is NOT your "best hope" -- it's the road to poor results.
Try the alternative suggestions above.

Btw, regarding Galvanisation is indeed a way to prevent rusting of iron, but your explanation is incomplete. There's a galvanic effect (cathodic or sacrificial protection) whereby zinc corrodes in preference to the iron.
OK -- that's actually good. You can just bump your Google searches to higher years and stop when you find a level that's more difficult than your classes.DifferentialGalois said:I browsed through some of the questions in the papers, but they seem to be easier than the tests we undertake at our school! Also, a lot of our questions have emphasis on application of theoretical knowledge, rather than rote memorisation of the topics if you will.

Probably something not configured correctly in your profile. Ask in the PF Feedback forum if you can't figure it out.DifferentialGalois said:Why do notifications seem not to show on my bell? *sighs*
OK, good.And regarding the sample questions I've posted, I put them to shed some light on the nature and difficulty of some of the problems I encounter during the test. The answers I put are reflective of how I might've answered them during a test, and gone through the process prior of thinking it out.
[...] regarding Galvanisation is indeed a way to prevent rusting of iron, but your explanation is incomplete. There's a galvanic effect (cathodic or sacrificial protection) whereby zinc corrodes in preference to the iron.
And now, the notifications have restarted , at least for me.symbolipoint said:Aside from the main topic, the Notifications Failure is happening to other members too.
The question is worth 1 mark and you have outlined (prompt word) 1 way in which galvanisation prevents rusting so you get the mark. If it was 2 marks and the prompt word was describe you might expect something more. Getting marks in exams is not about writing everything you know about a subject, it is about providing the examiner with an answer that fits the question.strangerep said:Btw, regarding Galvanisation is indeed a way to prevent rusting of iron, but your explanation is incomplete.
