We had a really nice conversation! Robert is very friendly and great to talk to. We discussed a wide array of topics, constantly keeping a steady conversation going. He seems to be genuinly interested in his students and encourages them to speak freely and openly about anything, but most importantly, about the things that interest them and will therefore yield the best study results!

Robert is very focused on the learning process and on identifying where the student can improve their skills. The lessons are always interesting and cover engaging topics. I have plenty of opportunities to speak and to understand exactly where I make mistakes, which helps me grow. For me, it’s a great way to polish my English in the best possible direction.

Had a great experience with Robert! The lesson is structured in a way that we can have in-depth conversations around specific topics, which is very effective in terms of practicing expressing ideas and learning vocabulary.
