There are different ways to learn a language: the traditional one and the practical one. You will achieve results with both of them as both are effective. The difference is how long  it will take you to achieve it. That is what really makes the difference. And no question, Skype is the best tool.  I´m a bilingual teacher which helps me make things clearer for the students in case they need further explanations to better understand. I have over 30 years of experience teaching Spanish as a second language which is more than a proof that my system really works. For you to make sure the kind of class is the one you expect to have, the first class is free. What do you have to lose? I promise it will be worth giving it a shot. No obligation..
