Ahhhh I love this essay question! I got a 9 in my English GCSE, so I can totally help you.
For your first paragraph, you'd want to do the introduction for Lady Macbeth, so all of your points would have to be in the first paragraph, not all of them together, but evenly spaced out. Act 5 scene 1 is when she sleepwalks, so you can make roughly 4 or 5 good points for Lady Macbeth after the introduction, such as
1. Despite being psychologically disturbed, she still has a commanding poise to her, as shown in "Out, damned spot! Out, I say!" (Use of exclamatives, and command words, etc.)
But Im not sure the question is worded correctly. Is it the whole play, or just the extract?
