In some ways you are very lucky because your experience of high school, hobbies and life experience will already be different from many UK/ home students so you should take advantage of this in your personal statement. But you also need to make 2 things very clear. Firstly, why do you want to study in the UK and secondly, you need to show that your English is of a good standard (usually IELTS 6ǌ or above). It is no good having IELTS 6Ǒ if you personal statement is full of grammar and spelling mistakes. But DO NOT pay for someone to write your personal statement for you on one of the many websites offering this service. If you have IELTS 6Ǒ, you do not have perfect native speaker style English and universities may reject your application if they suspect it is not your writing.
Check for grammar, punctuation and spelling. If you're not confident about these aspects then ask someone you can trust or hire a professional to check the personal statement. _ Review your statement and ask these questions: _ Have I answered the questions required? _ Have I put forward the best examples of experiences and effects that are relevant to my field of study or who I am? _ Have I effectively answered the main question here _ Why should the Graduate School accept me over my fellow applicant? _ Does this statement reflect who I really am or do I sound like a "too good to be true" parrot? _ Would I fall asleep if I had to read this or would it grab my attention? _ Have I let my sense of humor get carried away? Do I sound too opinionated or extreme in my views? _ Have I addressed any weaknesses I have e.g. low GPA or LSAT?
