I'm 40 years old, French, I have an engineering degree as well as a master in finance. I worked in the oil and gas in France until 2009. I've been living in Brazil for more than 10 years now and I teach French to 3 main types of students : people how learn the language for pleasure (normally I have had these students for years), candidates for the diplomatic career (CACD), and candidates to the DALF/DELF. With all of them, the exchange in the class in French is the base of a good progress as it helps to fix the language and understand the logic of the language. Whatever the level of the student is, I aim at having a discussion to incorporate the vocabulary, the grammatic, we're studying. After the lesson, I always send a summary of what we studied and homeworks.
