Presentation
The following points are a general guide for presenting assessment items.
- Responses to assessment items should be typed. Use 1.5 spacing.
- Use a wide left margin. Markers need space to be able to include their comments. Use a standard 12pt font such as Times New Roman, Calibri or Arial.
- Left- justify body text.
- Include a separate title page with your name, student number, subject code, assessmentnumber and assessment question. Include class time and tutor's name if applicable. Number your pages (except the cover page).
- Use a header or footer with your name and student number on each page.
- Always keep a copy of your assessments. Both a hard copy and an electronic copy.
- Most importantly, always use your spelling and grammar checker, but remember that this does not pick up all errors. You must still manually and carefully edit your work.
- You need to appropriately reference all the articles, reports and web-sites you employ in developing your assignments. Please use the APA style
