What Our Students Say

Real voices from real students who built fluency at Duke.

After I started studying here, my first impression was how dedicated the teacher was - explaining things clearly and in detail, and helping me improve my Thai speaking skills.

Huang Yu Ting
Thai student

I was impressed by the intensity of the classes, the enthusiasm of the teachers, and the relevance of the topics covered for my daily life in Bangkok.

Octave Galibert
Thai student

The teacher is truly passionate about teaching and genuinely cares for every student. Even the textbook is engaging — it never feels boring!

Yu Yung-Ting
Thai student

The vibe at Duke was so energetic. Everyone was smiling and full of passion. Of course, the English classes were interesting. It wasn’t just mechanical test-focused classes. It felt like I was truly studying the language. I learned both the language and the culture. That made studying more fun and meaningful.

Lee Yong Hun
English student

I liked the teaching style of the Duke school teachers from the first lessons. They are hardworking, they know how to explain and listen to us competently, giving us the opportunity to speak out. In 8 months I have changed 4 teachers and I can confidently say that each of them does their job well, but at the same time has their own unique charm.
