My scores on relevant exams were SAT 1540 (740 English, 800 Maths), TOEFL 113 and Romanian Baccalaureate: Maths 9.75/10, Romanian 9.90/10, Computer Science 10/10.
I have experience in many different areas and I consider that some of my most meaningful accomplishments are the fact that I worked in the National Student Government of Romania for 3 years, I completed an intensive Computer Science and Mathematics track in high school, and I competed in many olympiads (Debate, Maths, Computer Science, History, Geography, English). Apart from this, I am also interested in arts and humanities.
I have a lot of experience explaining new concepts and working with students (my age and younger) and I usually find it very easy to bond with people. I would also say that one of my greatest strengths is patience.
