Teaching methodology

My previous and current students include high school advanced level students and students from University of Connecticut (which is a member of "public ivy league schools"). During teaching, I would like to see students' engagement. I tried to make a session like a conversation instead of a monlogue. I prefer to give clear instructions to my students, usually in the format of bullet points.

Yu-heng - About your AP tutor

I have graduated from UConn on December, 2023, with a major in Mathematics & Statistics. Now I am a member of the United States National STEM Honor Society, as the Director of Analytics. On weekends, I teach some students about advanced computer class at New York City. I worked at UConn Quantitative Learning Center for 1 year, teaching students college level Mathematics & Statistics courses. When I was at college, my major GPA was 3.89/4.00. I also got full point in GRE Quantitative part (170/170). I have good knowledge in statistics (probability theory; statistical data analysis; mathematical statistics; statistical programming; etc.). I am also very proficient in SQL & Python & R & Excel.
