hopefully I can help you!
I've learnt that we should base our points around AO2, so the extracts language structure and form. And then we can bring in the rest of the AO's
Id start my points talking about the extracts language, structure and form since AO2 has the most marks after context! Then with each AO2 point (especially language as thats probably the easiest to talk about out of the three!) add in some references to context.. if the language has an informal angry tone to it for example, you could bring in why, like the authors past experiences or politics for instance, may have made the author angry and their language may reflect that. basically the authors identity reflects in the extracts language, structure and form
so, AO2 and AO4 could be woven in together, whilst using AO1 (terminology and creative and informed responses), and also making comparisons to your wider reading.
It may look daunting haha as right now it probably looks like this structure of answering the question will look like one fat paragraph haha. but with practice its really simple!
just think in each paragraph you could make a point about the extracts AO2's whilst also including the rest of the AO's! so each point can be one paragraph.
if theres nothing you can say about your wider reading with a point you've made then link the wider reading with context! after saying what you can about the AO2's then swiftly move on to context and compare then!
i guess theres no correct structure to answering this part of the exam since it depends how we perceive the extract that will appear, just remember: base your points and 'creative and informed responses' around lang, structure and form, linking them to as much context as possible, and if any of your points can be referenced to your wider reading then put them down.. all whilst using your appropriate terminlogy!
its honestly not as complicated and scary as ive put it, haha hopefully you'll understand what I'm trying to say!
