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.
5 _ Get help writing your personal statement _ No this doesn't mean get someone to write it for you! But getting help writing your statement can be very useful. Others can point out spelling mistakes you may not have seen, or point out how skills you have could be relevant. The very minimum you should do is get a friend / parent / tutor to look over it before you send it off. It could be the difference between acceptance and rejection.
