Mostly, my teaching is concentrated not on exam preparation, which is also possible, but on leading a person through the path of science, showing its hidden beauty and, hopefully, helping him/her to fall in love with the subject. Note about math and physics: I am more oriented on theory. My main goal is not to teach how to solve particular problems (which is also a very important skill to obtain), but to explain the logical chain of thoughts that led to the development of the whole field. In other words, I am leading a person step-by-step to a full understanding of everything that is going on in every equation and idea. Unfortunately, I don't speak German, only English, and Russian.
