Please need help proofreading an admission letter

Hi I am writing this admission letter because my family is moving back to our home country (Singapore) due to business reasons and my youngest daughter, who have been studying in Canada since kindergarten, has to leave school after grade 4. Since English is one of the main languages used in Singapore, communicating for her won't be a problem. Her biggest challenge however, would be the Chinese classes at school. So I am writing this letter to a private school in Singapore hoping it will help her catch up.

Dear Sir/Madam,

I am Mr. XXXXX and I would like to apply for my daughter's admission to XYZ's international class as a primary 5 student in September 2012.

My daughter's name is ABC and was a former kindergarten student from XYZ Kindergarten in 2006. She is currently in grade 4 studying at AAA in Canada.

She will be returning back to Singaore in June but my wife and I are concerned about her level of Chinese proficiency and whether she can follow the regular P.5 Chinese curriculum when she's back. But XYZ immediately come to mind because of its fine reputation, in particular, its Anglo-Chinese teaching system and its stimulating environment. I am confident about this because my elder daughter BB is an alumnus of XYZ and my son CC studied till grade 6 in XYZ. My nephew DD is also an alumnus of XYZ and have successfully graduated primary school in XYZ despite the fact that he was struggling with Chinese when he came back to Singapore from Canada when he was grade 4. Therefore, I am confident that ABC will have success both in her education and her overall development just like her brothers and sisters have in XYZ.

ABC is a girl with lots of potential. She is very sociable with lots of friends at school. She is very active and enjoys all sorts of activities inside and outside school, including regular academic classes, piano lessons, as well as skiing and snowboarding and many other activities. She said that her favourite subject is English because she can fully express herself through writing.

I know places in your school are very demanding but my wife and I will do all that we could to assist and guide our children in overcoming challenges they face. Hence I am writing this letter in hope that my application would be favourably considered. Thank you for your valuable time and consideration and I am waiting for your kind call.

Yours faithfully,

Mr. XXXXX
