SETTING OUT YOUR ESSAY:
The presentation of your essay is an important part of the writing exercise. Although we expect essays to be word-processed or typed, we will accept hand-written essays if they are legible. Every aspect of spelling, punctuation, grammar and formatting should be checked for correctness and the essay as a physical production should be as neat as possible.
Paper: Use standard A4 paper.
Margins: All margins should be at least 2.5cm wide. The left margin is often wider, to allow space for binding and/or marker’s comments.
Line spacing: Word-processed and typed essays should have double-spaced lines, for clarity and to provide space for marker's comments. If you are using a small type face, 1.5 line spacing is OK.
Justification: Left justification only is usually preferable to full justification (i.e. left and right but not centred), because the latter can introduce large spaces between words that interfere with readability.
Page numbers: should be on all pages but the first, where the number is optional
Submission: Corner staple your essay together with your completed cover sheet for the appropriate discipline, and put it in the appropriate essay box at SCMP headquarters (W6A 7th level foyer). Please don’t use paper clips that can get unstuck or folders/binders that make it impossible for the marker to write comments in the left margin. Likewise, plastic document sleeves are a nuisance for markers and are only liable to get separated from your essay.
