I had the luck of finding a weekend course for beginners in Latvian language here, meetings once a week. The school was easy to reach by public transport, since it was very close to the National Library, which is also a good landmark and a very well connected location. Our group was very nice, small and motivated, and our teacher made us speak a lot. She was encouraging and inspiring and had a clear plan how to guide us forward systematically using our coursebook and supplementary material. There's a lot to learn in the Latvian grammar just to get started, but I felt that it was presented in digestible amounts at a time with clear explanations and useful practice, and I'm sure more would have been given if we had asked for it. I'm very happy to have found this Latvian course.
