In fact I got 2 sacs, one in the first semester and last one in the previous term. My situation is a bit different. I've been studying among other native english speakers with other 2 esl guys. So I had to do the same sacs as native speakers but the assessment criteria was slightly soften for esl students. In the exam, I'm going to refer to the way by which I used to get over this stuff during the year. Also I don't have any idea about drawing arrows and how to summarise the piece in the best way at all. I think LA is worth less marks than others since it's all about reflecting your understanding to the paper with references to the article.
Poor you
I studied LA with Eng students last year and it was quite different from LA in ESL as they don't teach how to write note form. The way they analyse the article is also more specific and deeper than ESL. Note form summary which worths like 10-15 marks (I can't remember now), total LA is 30 marks, thus its equal with context (30 makrs) as well. Pretty important though
For context, its different from Eng as well. In ESL, examiners usually prefer expository form and they don't like imaginative or short story. Of course you can write in short stories but they don't recommend that for ESL students
Anyway, if you do ESL exams but study in Eng class, you can buy study guide and learn by yourself. I think VCE ESL exam guide or insight/outcome are both good. ESL exam guide mentions how to write note form summary for LA. Note that: NEVER write complete sentences in note form summary and you can use some abbreviation/ symbols like: ie, eg, ><, #, / etc...
