R&J - OK, I guess, but I would actually save that till secondary, because you want to see it for the first time when you're exactly that age & full of your own tragic intensities.
Like Coriolanus should be saved till you're a young adult. And Ant & C till you're, oh, at least forty-five.
Frogs, v useful - will save that. They did a little pretend Dream at drama club in the summer, so already have a bit of a sense of what's going on.
One last thing: do you lot remember having to do Julius Caesar first at school? That was because it's the only one which has No Sex In It.
