Dear Sir / Madam,
Thank you for the interest you have shown in our English Course in Cambridge Institute. I am writing this letter to reply and tell you some information about me.
First, I would like to provide you with some information about me. My name is zahraa and I am a 17 years old Bahrain girl. I live with my parents in Sanabis. I have different hobbies such us "reading and writing ". I am very active and keen on writing. I write some short stories and read English books.
As for my educational background, currently I am in my last year secondary school. I am in the Science track studding English, Arabic, Math and chemistry. I also studied Computer Science so I have very good computer skills.
I need to improve my English language as I have some problems with my speaking skills. I believe that doing with teacher will help me a lot. Moreover, spending summer in your institute will help me so I well study very well in the future. I am sure the course will be very beneficial in your Institute.
I look forward to hearing from you soon.
