I have tutored mainly math-related subjects for K-12 and college students for more than 5 years. I utilize graphs, interesting symbols, and a more user-friendly language to convey complex math concepts according to my students. I also teach conversational Chinese Mandarin. My goal is to let my students learn the subject efficiently and be prepared for exams, such as PSAT, SAT, or GRE, in a rather relaxing environment.
