Hello! I thank you for letting me assist you with the personal statement for your important application to UCL. I have made several changes to correct English usage and make several suggestions for changes that might add clarity and impact. I applaud your hard work and the well-focused steps you have taken toward the admirable goals you have established for your career and wish you much luck with your application! Please feel free to request me by name, if I can help you out in the future.
I thought the essay clearly and concisely gives your relevant background, and your interest in the subject clearly comes through.
