Help Please!!! Would you check my letter of interest for UniApplication?

I am applying to “xxx Foundation program” in xxx University starting in September, 2014. I will graduate from high school this year and I am motivated to start my higher education with this course.

I was born in Orenburg, Russia in 1997, then my family moved to Uralsk in Kazakhstan. Growing up in a bilingual country has allowed me to speak both Russian and Kazakh fluently. Besides Kazakh and Russian languages, I have been learning English for more than eleven years now. Thanks to my passion for English I became the FLEX (Future Leaders Exchange) program’s finalist. This program provides US State Department-sponsored scholarships for high school students from Eurasia to spend an academic year in the United States, living with a host-family and attending an American high school. Students are selected for their academic achievements, involvement in extracurricular and community activities, and personal leadership and organizational traits. Thereby, I am currently an exchange student in Colorado Springs, CO. I developed strong communication skills here. This year transformed me beyond recognition: not only I became more mature and liberate, I also changed my perspective on the world and on my own life. Discovering different ways of living and thinking is what makes being a foreign exchange student so incredibly beneficial. It turned out that everything is relative. I came to America in search of something new. This experience opened doors to opportunities I would have never thought to be possible, the world now seems much more approachable. The number of my interests and ambitions has increased exponentially. And, most importantly, I have gained huge confidence in myself and in my abilities.
As I can remember I have always been a Maths-inclined person. I have presented my Kazakhstani school in various competitions, regattas, Olympiads of city and regional levels. Mathematics and Physics always were my majors. They sort of disciplined and educated my personality. For example, if my mates were asked to describe me in five words, they would probably be ‘attention, patience, skepticism, sagacity, and enthusiasm’. Prompt and well-organized, I have been excellent in time-managing and money budgeting from the very early childhood. My parents bring along us, the kids, in a house where a new day starts with a breakfast and the world news channel on the background. We share our opinions on certain events, and discuss feasible solutions. It allows me to think critically and analyze life’s situations logically.
Despite of my excellent academic performance in all subjects at school, I prefer Mathematics the most. I found American AP Calculus course very useful for backing the determination to Maths of mine, as it provided an in-depth introduction to this Mathematics’ specific area. Overall, this experience had infused a strong conviction into me that I am able to successfully cope with programs taught entirely in English, and that I would really like to broaden and deepen my knowledge in this discipline.
Desired development cannot be achieved without growing up educationally. I believe that the XXX Foundation program will be a great start to my education path. As I am expecting, it would not only help on choosing a proper career (economics/ or mathematics/ or business studies), but also provide me with necessary theoretical and practical skills and enable me to prepare myself to achieve all my goals.
I would be very honored, if I were accepted to enroll for the XXX Foundation Program in XXX University.
