Hi guys,
It wouldn't be too much of me to say that I'm a pretty strong student in English, and have always been in the top 4 at my school in terms of marks. But the problem is, so far, I feel like I've just been improvising and winging my way through English. I feel that this wouldn't be beneficial to me anymore, (especially what with being in Year 12 and all), and also because it seems to me that my English skills have become somewhat stagnant. That is, I feel I haven't improved as much as I would have liked to, because I just relied on the tried and tested methods that got me through to Year 12.
I was wondering if anyone could give me any advice on improving my writing and vocabulary, and also outline the successful methods that you guys used to achieve top Study Scores. Just to clarify, I'm looking at getting a 45+ SS.

Thank you!
