I had a great experience with the knowledge school. Kru Boss is a terrific, engaging and approachable teacher and he worked well with students at a variety of proficiency levels. The school was flexible with my schedule, which was a big help with the limited availability I had while in Thailand. In the three weeks I spent in classes I saw a notable improvement in my ability to read and write in thai, and a notable expansion in my vocabulary. Kru Kee was also a great instructor. Both are kind, funny and did a great job pushing students to engage with the language. Love them both.
