Hi Victor, Welcome to the team. I wrote about this "promise" that we never get from these schools here: https://www.italki.com/discussion/125830 and also how to improve your skills here: https://www.italki.com/discussion/128253 I totally agree with you, you don't have to waste either your money nor your time with them (especially nowadays with so many things on the internet...), you only have to choose materials according to your needs and change them also according to your level needs. I am about to write three articles (in Portuguese to help brazilians) how to become your own teacher and I hope you like it. Soon they will be here. =)

Muito enganação dessas escolas de idiomas, estudo inglês por conta própria há 3 anos e já encontrei pessoas que estudam há 4 em escolas particulares que sabem bem menos que eu. Por que não consegue entender?, Por causa do vocabulário usado no filme que tu não sabes, ou por causa do sotaque?
