At the beginning of year 11, I would've given you a resounding YES! But now that I've learnt that English is all about memorising and churning out essays, I'd have to say that I'd most probably choose it.
Consider this: At the beginning of the HSC, prior to me knowing about memorising essays, I was achieving marks around the range of 40%. Nowadays, I'm getting 80%. That's a pretty massive leap.
Also, those who tell you that you must read to be good at english don't know what they're on about. I haven't picked up a book since year 6, and even then the only books I was reading were the books with the bite in the corner...what were they called?....Aussie Bites!
So yeah, my answer: I would choose the subject.
