Tips for writing your personal statement

Do your research
Find out as much about the course as possible. Attend an open day if you can - it's your chance to speak to the people who are going to be reading your application and ask them what they're looking for.
Get the basics right
This is the part of your application where you really sell yourself. Admissions tutors are going to see hundreds of personal statements, so make yours stand out. Make it easy to read with clear, concise sentences. Try to tell a story that gets across your message.
Why this course?
You need to convince the admissions tutor that you have chosen the right course for you. Focus on why you want to study that subject, and how your current studies and experience have prepared you for the course. You can also mention non-academic activities, but don't make this the main focus, and make sure you say what you learned from them.
Keep it personal
The clue's in the title. Your personal statement should be personal. Be positive, be honest and really get over your enthusiasm for the course.
