"Sonia is the best language instructor that I could find, and I would recommend her to anyone who is serious about becoming fluent in Portuguese. I don't say this lightly as I have already learned several foreign languages, so I have very high expectations towards my tutors; Sonia and her course have surpassed them by far. Before finding Sonia, I had tried some in-person and on-line lessons with different instructors, but I found that they either weren't able to explain the grammatical rules of the language correctly, or they would use English when teaching which delays progress. When I met Sonia, from day one, she only used Portuguese to communicate with me, really believed in my potential to learn, encouraged me to speak, and clearly explained any grammatical/pronunciation rules. Her materials are very well structured, they progress logically, and cover a topic in its entirety before moving on to the next one. Every lesson has exercises for testing one's understanding of the material which really helps recall better and grasp the practical usage of new grammar. Her grammar book is a great comprehensive reference, covering all topics and containing a convenient table-format guide on verb conjugation. Sonia and her course have really helped me progress, a big thank you for that!"
