A booklet with 10 Dystopian extracts for unseen practice. I think these are suited to OCR A level students and have included a short passage from Riddley Walker, not because I think it would appear in an examination, but because it is brilliant.
Several linked pages of model responses, with passages attached:
OCR A Level Unseen: Wyndham -The Chrysalids
A level unseen: OCR. Never Let Me Go
UNSEEN for discussion: The Time Machine. OCR A level
A level unseen: Dystopia (OCR)
