Unfortunately i think that's the case for a lot of people. I studied Midsummer Night's Dream for my O level & it was torture, we did the play to death, it wasn't till i saw a production of it at the theatre that i really appreciated how good it is. Far from the Madding Crowd Thomas Hardy was another one that i didn't enjoy at school but became one of my favourites when i read it as an adult. However, i do remember reading & enjoying Lord of the Flies & Smith by Leon Garfield in my English class.
