Hi all! My name is Zaur Tregulov. I graduated from the Faculty of Cybernetics and have been programming for over 9 years. But the most important thing is that I started teaching much earlier. Already during my student years, I taught mathematics to schoolchildren and prepared them for entering universities. It was then that the basic principles of my teaching methodology were formed: 1) everything should be explained using simple examples (most often from life) 2) the material must be explained completely (without any gaps) And it is this technique that allows my students to understand the whole essence of what is being studied subject. I am sure that the courses will bring you a lot of benefit, and you will be satisfied with them. Happy learning!

I am working on distance learning methods that make learning English easier.

I have been teaching for 18 of my 38 years. I started this activity while studying in the first year of the Faculty of Philology (English Language and Literature). I have experience in private and corporate teaching of English, Conversation Club, conducting oral and written translations. Since May 2014, I have been a certified specialist in the field of Communications from the London School of Business and Finance.
