❤️ This message is not just for rating Mixtree, it is an invitation to everyone who really wants to learn the language should contact with wonderful team!I searched for dozens of educational institutions. When I met Miss Kathleen for only half an hour, she supported me a lot.I started with private lessons with her, and I registered for a group course. (I don’t want to talk about the support they gave me because I would not finish if I started writing. It was a lot.) I did not speak English before because I was afraid to make a mistake.Since September to now, I finished B1 with Miss Clare group and now I will finish B2. (With private lessons with Miss Kathleen), I never believed myself, I had a good knowledge of English, but I only discovered it through my Mixtree teachers.The lessons are excellent in coordination, management and professional communication, If the rating was 100 stars, I would have given it with confidence.. I am not just a student, I am very grateful to them because they did a great thing to me, and I developed my work, I now hold meetings with official bodies in the English language (I am not a professional at speaking yet, but I started without fear).They are very dedicated, I don't see them working just for the sake of working, they love what they do❤️When I master the language well and find the time, I will not hesitate to help them as a volunteer to teach their students.Thank you wonderful team❤️

The teachers, the atmosphere, and the learning process are all truly captivating. The curriculum is exceptionally well-structured, making it impossible to become disoriented. The teachers approach their work with genuine passion, ensuring that you'll never find their lessons dull. After the courses, the desire to remain is strong, as you'll want to engage in a wide range of conversations and immerse yourself in the joy of experiencing diverse cultures.
