Some sentences and paragraphs read as though the writer has just tipped the half-digested contents of their head onto the page. This often means that the sentence/paragraph doesn't make sense to anyone but the writer, and maybe not even to the writer.

To ensure that what you have written does make sense, re-read all your work as though you were the marker. Ask yourself two questions:

is my point clear?

is it directly related to the essay title?

If your point isn't clear, and does not seem to be related to the essay title, you will lose marks.
