After a good assessment of my level, I joined a small group with students from different ages and countries, what made a very nice informal mix. The more so, since our teacher Vsevolod was very skilled and, moreover, a very pleasant person, also after classes… Thus, not only did I learn and practice a lot in all respects (reading, writing, talking, singing! and understanding), I really enjoyed the course, it is true value for money! I will certainly return soon, and if meanwhile the occasion arises, I will be happy to get into joint ventures with ProBa and its staff. Hearty recommendations from Arthur Olof, Amsterdam, Netherlands.
