Qualifications & Experience

I have been tutoring for 9+ years. I was hired as a TA and provided assistance to professors and students. I was also a math tutor in the Tutor Center of Science and Mathematics in community college. I solved many students' questions and held numerous review sessions. In addition, I also assisted advanced tutors with more advanced-level mathematics.

I got my Master's degree in Applied Math from Cal State Long Beach. The logic and analytical thinking I learned is really helpful to my tutoring career. I can now see questions in many different aspects and find the best way to teach students according to their aptitude. I enjoy helping students and I will keep doing it as long as I can.

Working with Yyun has been a pleasure. On the first lesson, he jumped right in on the subject matter with my son (Algebra I Honors). I was worried because my son's lessons had outpaced my skill set and I'm very good at math. Yyun knew his stuff. He is great at explaining things to my son and gives him lots of tips and tricks to help him in doing better on the tests. I'm very, very happy we have him as a tutor.
