Ich habe bereits in der Vergangenheit Nachhilfe bei Robert genommen, und er hat mir sehr geholfen, mich sprachlich weiter zu entwickeln.
Jetzt bereite ich mich auf ein Zertifikat vor und habe mich erneut für seinen Unterricht entschieden – und es war definitiv die richtige Wahl.
Am meisten schätze ich den individuellen Ansatz und die Anpassung des Unterrichts an meine Bedürfnisse. Anstatt einer starren Struktur nach Lehrbüchern konzentrieren wir uns gezielt auf meine Schwächen, was mir hilft, effizienter Fortschritte zu machen.
Die Grammatik wird klar, gründlich und auf eine verständliche Weise erklärt.
Besonders schätze ich die vielfältigen Gesprächsthemen – sie sind praxisnah, spannend und erweitern mein Allgemeinwissen und mein Sprachgefühl.
Wenn Sie eine qualitativ hochwertige und effektive Nachhilfe suchen, kann ich die THL Sprachschule nur empfehlen.

100% odporúčam! Zakúpila som si kurz nemčiny a za mesiac som sa posunula oveľa ďalej než za rok samo štúdia. Veľmi príjemný kolektív a učitelia nápomocní. Určite odporúčam každému kto sa chce učiť jazyky!

Taking this Dutch class over the last two months has been an exercise in both patience and discovery. Moving from a complete beginner to someone who can navigate basic daily interactions has been incredibly rewarding. While the language is famously direct, the class does a great job of showing that there is a distinct logic—and even a bit of humor—hidden within the grammar. Mr. Robert has been an essential part of the last two months, turning the complex rules of Dutch grammar into something manageable. His patience and encouraging approach make it safe to make mistakes, which is exactly what a beginner needs when tackling those tricky "g" and "ui" sounds. He doesn't just teach the language; he provides the confidence needed to actually use it. Rather than just following a textbook, he uses real-world examples that make the vocabulary feel relevant and alive. Thanks for his complete devotion and guidance. I am super happy about the progress i made till now...

I took Business English online course and it was definitely the best decision. Even though the course took place online I felt the presence of the teacher. The classes are super flexible. You'll really get answers on your questions during the class and the teacher is there for you. Highly recommended!!!

Robert je veľmi príjemný, trpezlivý a chápavý učiteľ. Nikdy sa nevysmieva ani nerobí srandu, naopak – všetko pokojne a podrobne vysvetlí. Vďaka nemu je učenie príjemné a bez stresu.

FAQ
1. Is it obligatory to attend the full 3 months of the course?
Group courses in English, German, Dutch, or Slovak last for three months and are divided into three separate 5-week courses. Continuing after the first or second course is not mandatory, but it is recommended and necessary to complete the full level and receive a certificate.
2. Is the language certificate valid in the EU?
No. Our certificates are internal and serve as proof of attendance and completion of the minimum requirements for achieving a given language level. They are commonly accepted by employers.
3. Do you also offer online language courses?
Yes, we also offer our English, German, Dutch, and Slovak language courses online via platforms such as Google Meet, Zoom, Skype, or MS Teams.
4. What do the courses look like?
Our courses are interactive. We place a strong emphasis on conversation, which is why our lessons are conducted in the target language (depending on the level). The textbook and materials serve only as a guide, and instructors never go through exercises one by one. Grammar is explained in a clear and simple manner.
5. How can I register for a course?
You can register for an English, German, Dutch, or Slovak language course on our website in the "Course Offerings" section. After completing and submitting the registration form, we will contact you within 3 business days to confirm the details and help you choose the most suitable language course for you.
6. Do you recommend a group course or an individual course?
There is no clear-cut answer to this question. Group courses are much more interactive, and our students often learn from the mistakes of others. Individual courses, on the other hand, are flexible and can be fully adapted to your schedule. You can also agree with the instructor on the content, focusing on the areas you want to work on the most.
7. Is it obligatory to take a stage test before the start of the course?
In general, this is not necessary if you are confident about your level. If you are unsure, we can arrange a short phone call or a visit with us to test you and select the most suitable course for you.
8. How long does it take to communicate properly in English, German, Dutch or Slovak?
It depends on the amount of material and practice you complete. For one student, it may take a few months, while another student may study for several years and still not feel comfortable in the foreign language. To reach level A2 (from A0), it typically takes about 1 year with moderately intensive instruction. Achieving B levels requires more time, as well as a few lessons with a native speaker or the opportunity to communicate with native speakers.
