I do AQA AS Eng lit B, but i got an A in my first piece of c/w!
My advise is to focus on your Assessment objectives. Form structure language, context, clarity of written expression (? if OCR has that in theirs), alternative interpretations etc.
Close analysis is vital for language. Symbolism? Motifs?
Oh yeah, for the grade A band we had to evaluate fsl, and critics etc.
E.g. "To an extent, yes, but one may interpret it as...". I know this may sound like key stage three stuff, but make sure you refer back to the question at the end of each paragraph!
For interpretations, try using a variety of them: e.g. marxist, feminist, post-colonial ?
It shows how you're going above & beyond.
I could help even more if you give me the title/topic of your coursework.
