Post up your context piece to the relevant board on AN (
English work submission and marking, there are people that can check your pieces, and give you in-depth feedback. Before you put pen to paper, spend some time making sure that your ideas are connected logically, and will flow without you having to over-explain them and make it a jumbled mess. On a 'paragraph-level', using good linking words and phrases (find a list online if you need to), will help you signpost your ideas and train of thought, thus making it easier for your assessor to understand what it is you're trying to say!
If your context is written in the expository style (the most popular option), get an in-depth understanding of what the VCAA wants from you: read the study design; assessor's reports; AN stickied threads and maybe even buy the AN Study Guide for English. All these resources will also help you with any other text type you choose for context.
Even if you want to do a persuasive or imaginative piece, it's important that you nail your expository pieces first: Expository pieces force you to research your context in depth, and also are more rigid in structure than, say, an imaginative piece.
Regarding what I do personally, I usually write down a small plan as soon as reading time is over, making sure I know that all my ideas will link and flow in a pleasing manner.
You should probably not post this in the End of Year discussion board though

, the English Studies section is where all the Class of 2013 should be posting
