I've only done 2 full timed exams. I tried doing another but I ended up writing 3 individual essays with a break between the first 2 and the last.
I'm writing on Stasiland and I absolutely love it. I've read it 3 times and my teacher says my knowledge of the text (for both TR and Context) is perfectly fine so I don't that's the issue. For me, says my teacher, the one thing that keeps my essays being 9-9.5 rather than a 10 is my poor expression. How do you think I should go about that?
Yeah that'd be lovely if you could. 
If your getting 9s, that it FANTASTIC! Assuming your teacher is marking them following the same standard as VCAA, then that is AWESOME! I'd be happy to get that!

Improving expression? The best way is to just practice writing more and more - There really isn't any other way to improve it.
I've copy/pasted this, so some stuff may not be relevant. Take from it whatever you want to.

The reason why I finish on time, is because I finish my Language Analysis and Context pieces within 45 minutes each. By doing so, I save at least 30 minutes.
How do I do this? For LA, I have been practising doing at least 2-3 per week (since June) and doing them within 45-50 Minutes (Sometimes 55 Minutes maximum). Because I've done it for a few months now, I've gotten into the habit of doing them within 45 Minutes. For Context, I have used one of my pieces that I got a very high score on. Because I've already got this piece done and can tweak it properly, I can write it out within 45 Minutes as well. If I really wanted to, I could push for 30-35 minutes, but I try and use my "extra time" to efficiently breakdown the prompt into pieces. I try to look at every aspect and ensure that I can tweak it properly. BTW, I don't plan my context for 10 minutes. :p In terms of TR, that is my weakest point, and I don't want to brag or anything, but its not dramatically bad. I try save time from my other sections and spend a little bit more on section a (TR). I feel that when I have more time for it, I don't feel pressured, and I can do it properly. With the remaining time I have left, I spend it reading over my three sections.
I think what helps, is to push yourself really hard. When I do each exam, I always begin my thoughts by saying "Okay, I have to get this done within 45 minutes".
When you do your first few exams, don't dread or get upset about them. Instead, try to use it as a motivator. Talking to your teachers about your exams also helps. Once a week, I sit down with my teacher and I discuss my exams that I've done. Even though it can be written down on paper (and she does do this), I learn more when I actually hear her say it to me. It also gives me an opportunity to ask questions about my work, such as "What else do you think I could add to this". The number of exams you do does matter, but its what you get out of them that matters the most. If you walk away from a practice exam knowing exactly what you did right and wrong, then you have done really well.
For time management issues, its something that most of the state faces. You gotta look at your strengths and weaknesses. Look at what your strengths are, and push yourself to do them within less than an hour (but still maintain a high standard quality). Then you will be able to dedicate more time for your weaknesses.
BTW, I think its pretty obvious now what order I do my 3 essays in, but this is the order: LA, Context, TR.
Hopefully there's something useful to you that I've explained. Let me know if you have any other Questions. More than happy to answer them for you.
