Dear Sir or Madam:
I am writing to apply for the Bachelor programme in Law and business. This summer I graduated a secondary school in Liepaja. I want to get a bachelor degree. All year I was trying to understand were and about what I want to study, but I have always thought that my future will be typed with economics or law. And a past to years I have thought about Riga graduate school of law, but then I was thinking that I am not plenty good, but now I` am. I know what I want and it won`t be easy, but I want to try. I live in **** and I always have wanted to live abroad I think your school can give me that, only because I will know English much more better that now.
I think I am good for your school, because I want to learn, in school I wasn’t excellent pupil, but I always have been in the middle. I have always been interested in law, I don`t know way. I have a responsibility about things that I have to do, I am kind and sociable. I have always wanted to study in English. I know that it won’t be easy, but I want to try and prove myself that I can do a lot of things.
Due to my wish to study in your school, I think I could deal with all much homework and study hard to reach something more. I want to live like people, I want a great education and good job and I have heard that in your school is one of the best educations.
I am looking forward to hearing from you.
Yours Faithfully,
