I took GRE twice, and got 800 in math each time. I do have a doctoral degree in Chemical Engineering. My doctoral research is about numerical study of rocket propellant combustion process. I also have experience teaching at both university and high school levels. Last year, I taught courses in AP Calculus BC, AP Physics B, Pre-Calculus, Physics and Chemistry in a private high school in California. Now, I am teaching a high school in Peoria, AZ.
My most enjoyable experience is tutoring. Last year, I tutored more than a dozen of high school and middle school kids in math, physics and chemistry. In addition, I taught SAT II Math Level 2 preparation classes, and the average score of my honor class is around 780!
