AP Calculus AB Tutor — Long-Term Online STEM Mentor

Most online tutors stay with a student for 6–8 weeks. Tae's longest-running students are in year 5.

Palo Alto Mentor is the online private practice of Tae Hyun Nam — a long-term STEM mentor for high-achieving high schoolers. Two families have been with him since 2021, working through middle-school math, AP coursework, and college admissions with the same mentor. Not the rotating cast of tutors that Wyzant, Preply, and Varsity rely on.

What Tae covers in AP Calculus AB

  • Unit 1 — Limits and continuity: evaluating limits algebraically and graphically, one-sided limits, infinite limits, asymptotes, intermediate value theorem
  • Units 2–3 — Derivatives: power, product, quotient, chain rules; implicit differentiation; inverse function derivatives
  • Units 4–5 — Applications of derivatives: related rates, optimization, mean value theorem, curve sketching, motion problems
  • Units 6–7 — Integration: antiderivatives, definite integrals, Fundamental Theorem of Calculus, u-substitution
  • Unit 8 — Applications of integration: area between curves, volumes of revolution (disk/washer/shell), accumulation functions
  • Exam prep: calculator-allowed vs. no-calculator sections, free-response problem strategy, May AP exam pacing

Who AP Calculus AB tutoring at Palo Alto Mentor is for

Best fit: 11th and 12th graders taking AP Calculus AB at school, students who want to score a 5 on the AB exam, and students preparing the foundation for AP Calculus BC. Tae's multi-year students often start in Pre-Calculus or earlier and arrive at AB with the foundation already built.
