$30Spanish online lessons with native spanish teacher for adults and teenagers
Trusted teacher: I am a native Spanish speaker and a general language enthusiast. In addition to Spanish, I speak German and English. I am 100% confident that I will successfully teach you Spanish (while having fun and relaxing)! I've been teaching spanish for 15 years. I am 41 years old, graduated with honors from the University of Salamanca. My main goal in teaching is to make students feel relaxed and comfortable while studying. Do you already know Spanish? No problem! Rather than building the basics, we can design courses to suit your personal needs and preferences. We can write essays together, you can give presentations on topics that interest you or that I present to you, we can discuss current events, engage in debates, you can write summaries of newspaper articles, or we can delve into advanced grammar. Whatever you enjoy and need, we can do it together. All my courses combine speaking, listening and grammar practice in interaction with me. Unless you are a very advanced student, we work with learning materials created by some of the best language learning publishers in Germany. These materials serve as a common thread for our course, introducing new words, grammar and exercises at a good pace and in an interesting way, keeping you engaged and motivated. I also show you German food, music and places. In addition, I will introduce you to the best technological tools (homepages and applications) to boost your language learning and take it to the next level. Another important factor for me is the personal connection. We usually start our lessons with how the weekend or previous weekdays were like. Contact me now to arrange a first lesson in which we can get to know each other so that I can learn more about you, your needs and desires and thus design the optimal course for you.

Dmytro
rating star
rating green star
I had my first class with Dmytro and I really enjoyed it. He takes his classes very seriously (he was very punctual, he had indicated to me in advance the apps/tools needed for the class, he was asking if I have questions, he replied very quickly to my messages before the class...). Also, he was very patient with me (I have a low level in chess...). I liked a lot that he was not just explaining "book" theory of chess, but also the practical tricks. I will book a second class. 100% recommended :)

Akbar
rating star
rating green star
Akbar is very professional and punctual. He was able to establish a connection with my son which in turn made him comfortable, and gave him a better understanding on the subjects he has difficulty from. I would definitely recommend him. His IB background is a plus to those like us, who wants to get used to the system of the program.
