Before you begin, you need to make sure that your browser is maximised (i.e. that it covers your whole screen). If necessary, you can do this by clicking the maximise button in the very top right-hand corner of your browser.
It's very easy to navigate through the questionnaire: just click on the answer or answers that apply and click on the "Next >>" button. If you wish to change an answer, click on the "<< Previous" button until you reach the required question.
Please do NOT use the browser buttons. You may need to use the scroll bar if you cannot see the whole screen at once.
