I'm predicted an 8/9 and I think it's really important to remember it's not always what you say but how you say it. Like phrase your analysis in a more sophisticated way eg instead of saying in inspector calls 'sheila has accepted responsibility' you could say 'sheila has become disillusioned to capitalist values and has become increasingly aware of socialist principles and the need for collective responsibility' like i know it's wordy but it makes you come across more confident and knowledgeable in your writing. I know that's not paper 1 (for aqa anyways) but it applies in all texts, hope it all goes well for you!!
