Writing at university involves setting out what you know and think about a subject, with evidence to support your reasoning. It must communicate your message to your reader and clearly signpost where they can find more information.
Why is it important?
Writing is still the predominant way in which knowledge is assessed at university and is an essential method of communication in many professions. At some point you will have to produce a piece of formal, referenced writing.
How do I do it?
Keep it simple. A lot of people mistake 'academic writing' for complicated writing but it is simply about getting across your message and your reasons, as clearly as possible.
