I have CAE (Certificate of Advanced English) given by the Cambridge University. I studied English since I was a kid of 6 years. I studied on the school for 15 years. I have worked in different companies where we used to be in contact with guys from Canada and US. I am used to keep me English in use daily as it has always been part of my life. I had students for English lessons once or twice in Mexico. Nous pouvons commencé français si vous croyez c'est possible, salut.
