I don't have a copy of the criteria with me but I can give you some general tips:
- Pick a good title that's wide (and interesting) enough to fill 1500 words, but not one so vague that you either don't answer the question properly or struggle to keep to the word limit. Keep it specific, but with plenty of scope to expand on your argument. Also make sure that it's a literary essay - it may be terrifically interesting and technically sound, but if you're not discussing literary features it won't score you high marks. As you're writing a WL 1 essay, make sure the topic relates equally well to both texts, or the essay will look unbalanced.
- Make sure your spelling and grammar are immaculate, and that your style/vocabulary are appropriate for a formal essay.
- Reference quotes correctly and consistently, and make sure they support the point you're making. Remember SEX - Statement Evidence eXplanation - so you make a point, reference or paraphrase from the text to back up your point, and explain why the point is relevant and how the quote supports it. If possible, find other sources (not just the texts in question) to support your argument.
Good luck! Feel free to PM me if you need any more help.
