Not all native speakers know how to explain the rules. I'll help you figure it out.

Hello everyone! My name is Guzel.
I’m a qualified Russian language teacher (I'm also a native speaker). I was born and raised in Moscow and graduated from Lomonosov Moscow State University, which is considered one of the best higher educational institutions
in Russia. And it is the only Russian university among the world’s top 100 universities in international rankings. My specialties are: Teacher of Russian as a Foreign Language, English teacher, and Journalist.
I prefer to speak only the Russian language during the lessons because it's the best way to learn a foreign language. However, don't worry, I'm also a professional English teacher and we will understand each other, either way.
I use communicative methods and provide modern authentic materials to create a natural atmosphere in Russian. I also pay attention to pronunciation. In addition, I work with All levels - from Beginners to Proficiency.
Don't hesitate to write to me, I'd be happy to help you with your Russian.
See you in my class!
