An informal e-mail:

Sergi,
How are you? How was last summer? Thanks for your email. I was busy with my homework so I'm answering you now.

I've got some great news! I passed the pet exam. One year ago I went with some of my friends to do some English classes for have the pet level.
When we all had the level, we went to Girona and we did the exam. Two weeks later I received an e-mail. This explained that I passed the exam. Have you got this level?

My other new is this. Three weeks later I started my first classes. I'm motivated because I think it's important to have a good level of English, because you need English to talk with the rest of the world.

I'd better go now. I must study.
Bye for now,
Abril.
