Here's something I posted on another thread on another board...
With English, not only should you be writing a lot of essays in the lead-up to exams, but try to perfect each essay you do. For example, let's say three weeks away from the exam you focus entirely on context that week. Write out a context essay and give it to your teacher to mark. Get some feedback from him/her and then write a new and improved essay the next day. Keep doing this over and over until you're entirely satisfied with your mark and feel that you can pull off a quality essay on the exam. You might be reading this and thinking 'crap...that's a lot of essays' but trust me, when you're less than a month away from exams then you will want to write heaps of essays - I never stopped and thought 'wow I have to do lots of essays' - just achieve your short-term goals and eventually your long-term goal will be reached. Another small tip: for context, make sure you have somewhat of a template or format to your essay that can be easily adapted to the prompt they give you. I had a fully memorised piece that could be adapted to any prompt and that saved me SO much time on the exam. Ended up scoring 10/10 for it.
There is such thing as studying for English without writing actual essays, such as practicing introductions, explaining quotes and writing up character profiles. I used the York Notes Advanced study guide for text response, seriously the quality of stuff in there is guaranteed to get you a 45+ if you read it thoroughly and jot down useful phrases that you could incorporate into any essay. Try to have a memorised introduction to your text response too, but of course one that can be adapted to the question given to you. I got 9/10 on my text response in the exam.
I'll be honest and say I did zero study for language analysis, matter of fact I probably did 5 language analysis essays for the whole year, I still pulled off a 10/10 for it on the exam but personally I found it to be easy (DO NOT DO WHAT I DID FOR LANGUAGE ANALYSIS - every person has their own strengths and weaknesses so this may not apply to you). I did end up getting 46 which I was happy with, but my teacher marked SACs very harshly. I'm not fussed now though.
