15+ years' experience -- math and science specialist! If you've been muddling along with precalculus or chemistry has you hitting your head against the wall, I've got your back! Focused but encouraging, enthusiastic but personable, I've patiently helped my students reach that "light-bulb moment" countless times. Guiding someone to understanding a concept they struggle with is of course a major part of tutoring, but I'm also really big on coaching students to be methodical and have a system. Content knowledge is only part of the puzzle; problem-solving skills are crucial. Check out my testimonials to hear from my students themselves on that!
About Stephanie O.

NOTE: I recommend 90 minutes for a first session -- in my experience, 60 minutes tends not to be enough to both get the lay of the land and deliver a reassuring and substantive amount of support. I look forward to working with you! I went to Princeton University and studied molecular biology. I was high school salutatorian (2nd in a class of 500+) and completed the International Baccalaureate (IB) program, while taking 11 AP classes. I've been tutoring continuously since high school, as both a private tutor and a volunteer, in subjects all across the board. I simply really love education -- both learning and teaching. And I always excelled at standardized testing, so I enjoy helping students succeed by taking the stress and mystery out of the verbal, math, and grammar/syntax questions on the SAT, ACT, and other common tests. --- ***MY BACKGROUND*** Volunteer tutoring in high school and college, private tutoring since 2008. Primarily with students in middle school, high school, or college / graduate school, but also late elementary school. Extensive SAT tutoring experience: one high school junior raised her math score by 180 points, and another student raised her total score by 140 points. Here's a highlight of my scores: 800 on the SAT Verbal section and the SAT Subject Test for Math Level 2; 740 or higher on my other SAT sections and Subject Tests; on the GRE, 164 Verbal, 169 Math; and 5 on AP Biology, Chemistry, Calculus AB, U.S. History, English Literature & Composition, and Spanish Language. I was an English co-instructor for three months in a private university in rural China and obtained certification in Teaching English as a Foreign Language (TEFL).
