ahhh I am panicking slightly too... I've been doing poetry revision ALL day, I still need to revise some maths as well...
Also, I read the OCR report for the Jan 2012 exam and the comment under one of the prose essay questions was 'As ever, candidates seemed to be more attracted to questions about characters and themes than to those about language and structure' which hints what the two essay questions might be! My teachers have been saying they might be more lenient because it's the first year, so fingers crossed....
