What we learn and how we learn depends on your needs. We can prepare for exam, fix your school problems if there are any, get better understanding how the science works. This is not a school - I always want my lessons to be effective but I also want mu students to like them. And they do. I've got Master's Degree on laser physics, I worked at the university, secondary school and many years in business where I was also constantly using my educational skills. I have years of experience in online teaching and a great number of happy students. Working together there's hardly anything we can't figure out. I'm working with primary school kids as well as with university students. I like teaching and I like my students.
