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.
The personal statement is one of the most important requirements for college admissions. Along with your GPAs, SAT requirements, and recommendations, a high quality personal essay is one requirement you should never leave out. There are many ways for you to make your essay more compelling than others, such as looking into personal statement examples as guides. Nonetheless, you can also screw up your admissions essay by committing the above_mentioned mistakes. The important thing is to stick to the rules, while writing a lively, original, and creative personal essay.
