Now you are looking at the remaining 20% of your word limit being your conclusion. Percentages may vary if larger word limits are being offered. Ensure you state why you are interested in this field of study; state the key points from the body of your essay (e.g. accomplishments, experience and interest). Ensure that you keep it brief, to the point and leave out the clichés. Just as you started your personal statement with an attention grabber, make sure you finish your personal statement with one or two sentences that are positive and leave the reader remembering your statement while they are reading the next few.
Then look at some resources for writing personal statements and get some advice. There are lots of websites which will offer you advice for writing a personal statement but it is best to look at websites from reputable organisations such as UCAS or student advice websites which are well used such as The Student Room. Remember to ask your teachers, friends and family for advice. A good question to ask them is "what do you think makes me different from other people? or "how would you describe me?" because the answers often give you some interesting information that you hadn't thought about. The personal statement is not something you can write quickly so be prepared to think a lot about yourself, your qualities, skills, experience, likes and dislikes. You are unlikely to meet the people who read it so your personality needs to come though on paper; this is difficult.
