IELTS Writing Task 1: technique review
Let's review the approach (method / technique) that I suggest for writing task 1. Your task 1 essay should contain three elements:
1.You need a short introduction to explain what the graph, chart or diagram shows. The easiest way to write this is by paraphrasing the question. The examiner will be impressed if you can paraphrase effectively.
2.You need an overview of the information. This means that you need to look at the "big picture", not the individual details. I recommend writing a short paragraph with two sentences that summarise two main things that you can see on the chart. If you forget the overview, you'll get a lower score.
3.Finally, you need to describe some specific details. This is where you select, describe and compare individual pieces of information (usually numbers). I try to separate this description of details into two paragraphs.
