WELL. it's much harder than yr 10 and yr 12, because it's so different from being in yr 10. you kind of take like a big leap over suddenly preparing for the HSC. but don't stress out so much, and manage your time well, i think is the best advice i can give. and everything will be okay (: it won't be as hard. it's only super hard for people who procrastinate a lot, because then you spend most of your time trying to catch up and it's stressful!
