I am Vitalie and currently, I am a master (MSc) student with a specialization in advanced technologies.
I've started tutoring when I was 17 years old, by helping my classmates with different subjects, such as math, physics, chemistry. Later I developed a passion for tutoring. I have experience of 3 years in tutoring international students, especially in physics and astronomy. Occasionally, I was tutoring in a winter camp of astronomy and astrophysics in my country. From my past experience, I have built a great background and improved my tutoring skills and now tutoring became a part of my life.
