Hey, with expository essays for context, I generally use books/movies/world events/etc. However, if I get stuck on trying to think of one then what else could I use instead? Are social references ok to use if you're aiming for high range essays or do examiners dislike them?
If you're stuck, you can write about 'famous' quotes relevant to the context and prompt. Not sure what you mean by social references? Try to support ALL examples with quotes, quotes and more quotes! Eg. if you want to write about the Stolen Generations, that is great, but you need to find some quotes from prominent Aboriginal leaders or maybe politicians that are relevant to that & can be used in essays. An example is nothing without quotes, since there's nothing to back it up.
I would strongly suggest that you know a few movies and songs really well, and know quotes for them, because these are the easiest to remember under pressure. The quotes will be easy to remember since you would've heard them. If you're doing a song you're already familiar with, that's great since you will have no problems remembering lyrics in the exam

This is a similar question to above in regards to what is acceptable for high marks in the exam.
In regard to expository essays, if I am employing a personal style, would it be safe to use this structure
1.paragraph 1- personal anecdote + text
2.paragraph 2- personal anecdote +psychological example
3.paragraph 3- text as well as psychological example
E.g If I am writing in the voice of someone and the prompt is about exploring perceptions, and I look back and reflect on experiences this particular voice has had in regards to that etc.?
Its just i feel I can't write a straight expository style, so I have a lack of real world examples I can weave into the style I'm using
Sorry if this is a weird question (!)
Yep, that looks like a great structure! Not sure if you planned on using both your context texts, but you will not or should not do it with that structure. Use just the one text. Not sure what you're saying in the 2nd question???
