Tutor in Irvine, California

I'm considered by many to be considered a mathematics/science whiz (I know math up to Calculus III, Differential Equations and Linear Algebra). As a result, I would be willing to tutor anybody academically in math classes (Pre-Algebra, Algebra I, Geometry, Algebra II, Trigonometry, Pre-Calculus, Calculus, SAT I Math, SAT II Math; I can also assist in US History). So if you people have someone who needs improvement in one of the above subjects, I'd be willing to personally assist them. Rate is $20 per hour (cheaper than what other tutoring organizations offer); each session is a 2-hour session consisting of serious drilling through problems and quizzes.
