I liked Ruslan's lessons for several reasons. First, the form of conduct. Warm-ups, interesting tasks with the search for analogies and many other exercises, built in the form of games, encourage you to refresh your knowledge and gain new ones.
Secondly, Ruslan pays attention to every student, no matter how communicative he is. So, even if you are shy to take the initiative, you will not go unnoticed and will take part in the class on an equal footing with everyone.
Third, the teacher not only easily and logically explains grammatical structures, but also complements them with related materials.
I advise Ruslan to all who study English. In particular, it is very easy to understand for representatives of specialties far from philology (for example, mathematics), because his method is really very well thought out and logical.
