I took a FIDE test today. I was very nervous, but I was really happy to see the kind and warm faces there that helped me feel more at ease. The receptionist was also very informative and helpful.

November 2024. I took the TELC exam at ILS Basel and was very satisfied. The exam was well organized, the atmosphere was calm and friendly, and the staff was professional and attentive. Everything went smoothly and pleasantly, and I came away with nothing but positive impressions.

Thanks to ILS Basel , I can now write my review in German! I first took the A2 course here, then the B1 and B2 courses. 🎉 I’d especially like to mention my teacher, Chris Stettler, who taught me in both the B1 and B2 courses. 🌺 She always encouraged me to speak up, improve my German, and not be afraid to try new things. Chris is a wonderful teacher—friendly, patient, positive, very knowledgeable, and extremely dedicated. She answers every question thoroughly, explains everything in great depth, and takes plenty of time for each student. Her motivation and enthusiasm for learning German are contagious, and you can tell right away how much she cares about her students. Anyone who has the chance to learn from her can consider themselves truly lucky! 🪷🌸🌺 I also often attended the conversation classes on Fridays from 5:30 to 7:00 p.m. Chris is always exceptionally well-prepared, brings up interesting topics, and makes sure the classes are fun. 🌞🌻🗣️ You meet nice people, can make new international friends, and learn a lot in the process. 🌎 ILS Basel is very well organized. The classrooms are clean and nice, and the staff in the office is very friendly. 🤗🇨🇭 I plan to take the TELC B2 exam here as well. Many thanks to the entire ILS team, my first teacher Nathalie (A2—my review in English), and my other teacher Chris Stettler! ♥️

I recommend improving the audio quality during the listening test, perhaps by using a device other than a laptop.
