What can I do to enhance my application?

Ensure that you show on your application that you fully understand what the course you have applied for is about (eg you know what subjects are taught on the programme and the relevance of those subjects not just the title!), and how the course meets your own personal / career goals. Show that you have an understanding of the skills and competencies required for that particular course and how you have developed these in your own personal / working life / prior education. Do some research into what graduates from that course do afterwards. Highlight any study you have done in the past or recently - even if it is just a short course in something unrelated - anything you have done shows motivation, commitment and a desire to learn.
