I have an experience of private tutoring in physics and mathematics at high school and university levels. I have long time experience in teaching calculus (both differential and integral parts) as well. Currently, I am a lecturer of physics and Wolfram Mathematica in the Armenian State Pedagogical University. I can teach in English, Spanish, Russian and Armenian. Besides practicing teaching, I am also a researcher in nanoscience, and for me, teaching is the only true way to share the knowledge and experience that I have. I give a student all the necessary information to understand the theory that underlies any problem. At the same time, I give a student all the freedom to interpret a problem in his own creative way.
