Jessica's path through a Penn history degree and medical school required constant fluency in math — from college algebra and calculus to the quantitative reasoning embedded in scientific coursework. She breaks down arithmetic, fractions, ratios, and word problems by connecting them to practical scen...

From simplifying algebraic expressions all the way through integration by parts in AP Calculus BC, Kate covers the full span of middle school and high school math. Seven years of tutoring means she's seen where students consistently get stuck — like the jump from arithmetic thinking to variable thin...

From pre-algebra fundamentals through calculus and linear algebra, Jai's engineering background means he's used every branch of math students typically encounter — and used it under pressure. He's especially sharp at showing why a technique works, not just demonstrating the steps, so that students c...

From pre-algebra fundamentals through multivariable calculus, Rhea covers an unusually wide range of math — and her 36 ACT and 1550 SAT back up that breadth with results. She digs into the reasoning behind formulas and procedures so that concepts like function transformations or integration techniqu...

Erika covers math from pre-algebra fundamentals through calculus, with particular strength in the middle and high school range where gaps in foundational skills tend to snowball. She diagnoses exactly where a concept breaks down — whether it's fraction operations, equation balancing, or function beh...

A mechanical engineering PhD means living inside math every day — differential equations, linear algebra, multivariable calculus, and everything that builds toward them. Jeffrey uses that depth to explain foundational topics like fractions, proportions, and algebraic reasoning in ways that prepare s...

Studying Applied and Computational Mathematics at Caltech, Samuel breaks down everything from fraction operations to polynomial functions by connecting each concept to the reasoning behind it. He served as a teaching assistant for a discrete mathematics course and ran an SAT prep class in high schoo...

Quinn covers math from foundational algebra through calculus, but his real strength is diagnosing where a student's understanding breaks down. A shaky grasp of fractions can quietly sabotage someone in pre-calc months later, and he's sharp at spotting those gaps early and closing them before they co...

Whether it's fraction operations tripping up a fifth grader or function notation confusing a high schooler, Pinelopi pinpoints the specific concept causing the breakdown. She covers everything from pre-algebra through pre-calculus and earned a 1530 SAT, so she can connect today's math lesson to the ...

Sharon spent a full school year embedded in a classroom with students performing in the bottom 10th percentile in math, and a quarter of them jumped roughly 15 percentile points by year's end. That experience taught her how to identify exactly where a concept breaks down — whether it's fraction oper...
