I'm resitting this exam as an A2 student on Friday - last year I didn't revise at all, didn't know the AOs etc and totally bombed it and got a C. Feeling the pressure as I need an A this time! This year I've revised completely differently and I feel a lot more confident. Last minute stuff:
Section A 1 hour: the first question is basically all AO2 so just talk about Setting, Form, Structure, Language and Narrative Voice. You don't need AO4 or AO3 at all here, and including this will just waste time (made that mistake last year!). Go through all the chapters/sections that might come up and make brief bullet points of setting, form, structure, language and narrative voice points.
The second question is on AO1, AO3 and AO4. So you need to support your argument by talking about the context of the text, and by discussing different critical views. You don't necessarily have to quote critics, but be open to different interpretations. Don't spend ages analysing language in detail, it won't get you marks.
Section B 1 hour: All the AOs! Roughly 20 mins on each text. Talk about language, structure etc (AO2) then back up all this analysis with a bit of context (always relevant, not just bolted on) and an alternative view or two. Don't forget to read the question thoroughly - 'how significant is..' is completely different to 'how does the author use..'. Top marks in all questions evaluate, so really evaluate your points and your response to the question.
Do some past papers, or if you haven't got time plan essay answers. Look at critical views. Learn the context of each text. Practice language analysis. Know your texts!
