Great that you're getting ready so early

A couple of my own tips:
Focus on the concepts, not just the exercises. Make sure you understand everything completely, and in every way that it can be used; eg different contexts, different wordings. This will help immensely with your Exam 2 (which is the bigger exam).
Do hard questions. Don't rely completely on the textbook; if you can, look for really difficult ones. This is what my friends and I did, resulting in us finding both 2011 papers pretty trivial compared to the practice we'd had.
DON'T give up. Methods was grueling for many of us, but pushing on and working helped immensely. I personally gave up Methods in the middle of the year, but worked really hard at the end and did ok. I guess I kinda regret not working harder throughout the year, had I realised that it wasn't going to be in my bottom 2

I can't stress enough how important fundamentals are. Whatever you do, you need your fundamentals. This is the reason people find Exam 2's so hard.
Also, find your weakness. Which is your weakest topic? For example, from Year 11 I realised that probability was a huge weakness. So when my school taught it, I payed extra attention

Then when it came to preparing for the exams, I looked for other probability stuff to do, and brought it up to make it my strongest area of Methods.
Also find your weakest exam technique. For me, it was carelessness. I regret not working more on it than I did; I ended up having to work extra hard at the end to pull my marks up. (My Exam 1 started out at around 30/40). Try to work on these issues throughout the year.
Good luck, and feel free to PM me for extra tips
