EXERCISE 1: Application form.

Dear Mr Kennedy,

I am writing to apply for the position of sports leader as advertised in last week’s newspaper.
I have a lot of experience in sports. I started practicing sports when I was at school. I took part in both swimming and basketball teams, and afterwards (this is not incorrect but is just not needed) I continued playing when while I was at in the university. Nowadays, I am working with young people in a college, so I would be able to work as a sports leader (this is not incorrect, but it would maybe be better to say, "so I have the skills needed to work as a sports leader").
I have four brothers and sisters, whom I often and I usually have to look after them when my parents are working. So I am used to playing with children and takeing care of them. Furthermore, I speak English and Spanish.
I would be willing to like to be able to relocate at short notice, but unfortunately I am staying at college until the 15th June, so I could be ready for this time to relocate at that time.

Yours sincerely,

Juan Ramón Yago Bustamante

Juan - this is a great entry with very few errors, well done! Just wondering if when you say college do you mean university? I'm not sure which country you are addressing this to, but in Australia & I think British English, we use university instead of college and primary school for working with children.
