I'm currently in my last year of graduate study in the PhD program of applied mathematics at the University of Southern California. I have been a teaching assistant for 4 years and always have excellent review from my students. I'm good at problem solving and all types of questions and tutors on mathematics. I am a nice, patient and humorous guy and know how to make students understand maths better and deeper. I also had training on mathematics olympiad competition before. I will be glad to help you.
