I did The Wife of Bath's Tale; was thoroughly resistant to the idea of reading Middle English, but it turned out to be the start of a love affair with Chaucer that has (so far) been lifelong. Twelfth Night, like you. My second-year coursework was on The Buddha of Suburbia and The Rotters' Club, both of which I adored, thanks in no small part to the teacher, a lovely man who bought us all The Closed Circle, the sequel to The Rotters' Club, and said, "It's not a set book, so you don't have to read it, but I thought you might like to" (we all did - a testament to his influence as much as to Jonathan Coe's writing). That's all I can remember now. Oh - Donne's "The Flea" and Hemingway's "Cat in the Rain" both came up, but I think only as practice for the unseen text.

Sounds like you've got a good crop of stuff to read overall - well, apart from A Passage to India, from what you say - I've never read it so I wouldn't know!
