What makes a final report look terrible?
First impressions really are important with coursework. You not only want your work to be brilliantly easy to read and navigate (by using report-writing style), but it should look the business and make the marker be impressed just by looking at it! The simplest way you can ensure this happens is to use a template. There is nothing worse than a report of 50 pages that uses 5 different font styles and 10 different font sizes, different layouts for paragraphs on different pages, with headings that are sometimes in colour and sometimes in black, that are sometimes underlined and sometimes not, with page margins that are different on different pages, with spacing out between sections of writing different on different pages and so on. If you pick up any book and flick through a few pages, it will look brilliant because there is a consistent style from each page to the next one.
