1. Slow Writing
Once you've finished any piece of writing in class you get to improve.
Read through your first sentence. Interrogate every single word and consider whether there might be a better word. Look at the first sentence and ask, could it begin differently? Should it be longer or shorter? Are you absolutely sure it makes sense?
Repeat this for first paragraph.
Now look at the first paragraph and think about how it works. Are all the ideas connected?
Now, moving into the second paragraph: does it flow logically? Does paragraph 2 pick up where the preceding one leaves off? Is there variety? (The examiner is particularly keen on one sentence paragraphs.)
