Michel Thomas Foundation Course: Spanish (Michel Thomas) - Michel Thomas

Great method of teaching and great format with the two students and one teacher. Very enjoyable to learn a language this way.
But ..... there is a number of mistakes in the material. My girlfriend is Spanish and it was great to show off my newly learned phrases when talking to her on the phone or writing them in an e-mail or sms. However it was quite disheartening to hear that some of what I had learned was incorrect. For example, 'reservation' is not 'reservacion' but 'reserva' And the imperative for 'tu' is simply taught wrongly. And the present perfect for 'escribir' is not 'escribido' but 'escrito'. Obviously my girlfriend has not listened to the full course, so I'm worried that there may be (many more) mistakes.
So a great course and I feel I have learned a lot about the beautiful Spanish language, but only with the help of my girlfriend (who by the way is even more beautiful than her language).
