Hi Sarah Lee,
A couple of recommendation on format:
- check with your tutor how many words are expected in your final exam answer - this will help you to decide what level of detail should be included
- keep in mind that you can attach a file with your answer in your favourite format e.g. word or powerpoint. This is much easier than using the limited editor on students portal.
- make your answer easy to read highlight the most essential elements of your answer.
If you combine this with your knowledge of the subject the result will surely be positive! Good luck!
