There are few ways to more clearly make impact than tutoring. You first meet with a student and the situation's "hopeless," but you help them slow down, breathe, and dig in, and within a few weeks they're master of the impossible. Little in life is more satisfying.
I am an experienced private tutor; over the last 7 years, I've worked with college, high school, and middle school students on SATs, LSATs, GMATs, ACTs, Regents Exams and SAT Subject Tests, as well as a lot of admissions application consulting. I believe that the best tutors are true masters of the content that they teach, and I have the results consistent with this - 2400 SAT, 175 LSAT, 760 GMAT, 800s on several SAT Subject Tests, and 5s on multiple AP Exams.
I take a common-sense approach; strong performance comes from hard work and understanding your mistakes. A lot of students put in the hard work, but they never process what they're doing wrong, so the repetition doesn't compound into improved understanding. Making sure that compounding happens? That's where I come in.
