"I am an experienced tutor from the most prestigious tutoring companies in the Bay Area, and I taught physics for years in universities. My tutoring focuses on physics, high-level math such as calculus, and test prep. Most of my students are high school juniors, seniors, and university students (mostly from Stanford). My regular students saw one to three grade points improvements; my AP test prep students saw one to three grade points improvements with just three to five sessions; and my SAT Subject test students saw 70 to 180 points improvements out of 800. My recent five students in SAT Physics and Math Subject tests received 750, 770, 800, 800, and 800 (out of 800)! (And the one who got 750 was getting 800 in his last a few practice tests.)

My very first student needed help to get a B in physics and, with my help, got an A! My very first SAT Physics Subject test student improved his score from 610 to 790 (out of 800) in his practice tests. My very first one-on-one class student learned half a semester’s material in 7 sessions, gained in-depth understandings into the true meaning of calculus, and became confident in jumping from middle-lane pre-calculus into the fastest-lane calculus. His mom added, “Thank you so much, Leon! I know you’ve definitely put his mind at ease, too!” These are just the very firsts — they say one improves with experience. A recent student who "will be very happy to get a C" (meaning was doing worse without my help) got an A-! And that was in Linear Algebra, a very abstract and difficult class at Stanford University, competing with the best of the best in the nation!

My students frequently ask me to teach/tutor them in other subjects and/or their younger brothers and sisters. After the very first session in physics, my very first student (mentioned above) asked me to also tutor him calculus. Later, his mom asked me to tutor his younger brother in AP Calculus and AP Physics. My first one-on-one class student (described above) asked me to help him with his precalculus/calculus course aft" less...
