I agree with writing by hand.
Honestly, the things that are going to prepare you for Year 12 English probably aren't going to be Year 10 or 11 English

. Of course, do your homework and whatever else but, the best things you can do to prepare for English are as follows:
- Get an exercise book and call it your vocabulary book. Every time you hear or read a word you don't know of, look it up and put the word in here. Use the word in a funny sentence, maybe read over the book every so often.
- Read as much books as you can. Not just random fantasy/sci-fi books like I am Number Four (good series though), challenge yourself a bit, too. When I was at the end of Year 9 I was heavily into S. King books and they were pretty decent. If you aren't being challenged by anything you find, come back here and ask for some appropriately challenging books.
- Keep writing as much as you can

. Start a blog and write in it every fortnight or week or something (or more, if you have more to say). Do whatever you want with it, but pretend as if five hundred people are going to judge you for shitty writing and write as clearly as you can

. When you read over your old blogs every so often, you'll start to judge your own writing and improve even more anyway.
- Be a cynic and hate the media.
