Trusted teacher: Hello everyone, I'm Thaer, a specialized teacher in Arabic (Formal, Levantine, Gulf) & Turkish language. With over 10 years of experience teaching Arabic in Lebanon, Turkey and UAE, I've helped NGOs, journalists, and embassy staff swiftly grasp the language for effective local interaction and business. Additionally, I've supported young learners in understanding Arabic's structure, laying a strong foundation. Most common questions I receive: What dialects do you teach? I teach Formal Arabic (Fus’ha) in addition to Levantine and Gulf dialects. Which one should I choose? It depends on your needs. If you are solely interested in speaking, then I recommend Levantine or Gulf dialects. If you aim to master Arabic comprehensively, then Formal Arabic (Fus’ha) would be more suitable. What is the 30-hour program? The 30-hour program is designed to help you achieve conversational fluency and effectively express yourself and your needs. What comes after the 30 hours? If you are enrolled in the Dialects course, we will continue refining your speaking skills and expanding your vocabulary during lessons. Additionally, new words will be introduced during conversation sessions to aid in memorization and usage within sentences. For those on the Formal Arabic (Fus’ha) track, we will delve deeper into grammar and further develop your understanding of the language. How many hours a week do you recommend? I recommend 2 to 3 sessions per week. Can I learn Formal Arabic (Fus’ha) and one of the dialects simultaneously? Yes, you can take 2 lessons in Formal Arabic (Fus’ha) and 1 lesson in a dialect concurrently, as many of my students do.

Private Math Tutoring by Experienced Teacher For all Levels. (Rome)
Hamid
So far, I have had two sessions with Hamid and the experience has been pleasant. I find that Hamid was well prepared before the classes began. He made his own notes, schedule and was very organised with his approach as a tutor. Professional, clear about his teaching methods etc,. As a tutor, he is very patient and explains everything with a simple and understandable analogies. I am happy with his teaching and hopefully will continue to do so. Highly recommended.

Find your singing voice. A safe and natural technique to sing classical, opera and music theatre. (Cheste)
Lynette
I have taken my first lesson with Lynette and it was a great experience. I have been singing for some time at a choir, but have no formal training and want to learn the fundamental technique, and also work on some of the pieces we sing at the choir. The lesson was very practical, dynamic and she pays great attention to detail. After the class I could feel the improvement on the areas we have covered and felt much more confident on my skills. Highly recommended!

Piano Lessons with Lasha ( Find out more about music) (Zurich)
Lasha
I took a few lessons with Lasha so far and I had a great experience. Lasha is diligent in preparing the material for the sessions and he adapts the lessons to my specific level and to what I prefer to practice which allows me to progress in the directions I'm most interested about. Otherwise, Lasha is an easy going and nice person and I can happily recommend him to other students.
