Font and style: Use a legible font of at least 11 point, and spacing of 1.5 lines. Use subheadings as you wish. Please make sure you use page numbers.
Title page: Your essay should have a title and you should give your matriculation number only on the title page (not your name).
Word count: The word count limit for your essay is 3500 words. This does not include words in the reference list, in figures and tables, and their legends. Going a small number of words over the word limit is unlikely to be penalised. Please give the word count on the title page.
References: you can use any recognised scientific style for your essay – Harvard (author-date) or Vancouver (author-number). Your reference list should include the title of any paper you quote. If in doubt, follow the guidelines for a scientific journal e.g. Plos Pathogens http://journals.plos.org/plospathogens/s/submission-guidelines#loc-references.
There is no minimum or maximum number of references – this will depend on the topic of your essay and if in doubt you should discuss with your essay tutor.
