In year nine we did Frankenstein. We covered it for our SATS. We didn't go into as much depth as anything we did at GCSE but I think we spent most of a term on it.
I might be misremembering, it's been a long time since I was 15. But the one fact I took from these classes was that Mary Shelley had experienced a miscarriage. This was the unnatural, horrific event which explained the monster in the story.
