Prof: "Here're a few examples of what you should aim to achieve in your assessment. This one's a PhD thesis, and these are (very long) journal articles. Now do the same thing, but in 1500 words. Oh, and this is 40%, not 30% as was previously stated, of your final grade."
For fuck's sake. The literature review alone for this kind of thing should be a good 2000–3000 words.
