AP Calculus BC Tutor — 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 BC

  • Everything in AP Calc AB — limits, derivatives, integrals, applications — reviewed and extended
  • Advanced integration techniques: integration by parts, partial fractions, improper integrals
  • Parametric, polar, and vector functions: derivatives and integrals in alternative coordinate systems
  • Infinite sequences and series: convergence tests (ratio, root, comparison, integral, alternating), power series, radius of convergence
  • Taylor and Maclaurin series: generating series, error bounds, common series memorization
  • Differential equations: Euler's method, logistic growth, separable equations
  • Exam prep: the BC exam is paced differently than AB; mock FRQs with detailed scoring

Who AP Calculus BC tutoring at Palo Alto Mentor is for

Best fit: high-achieving 11th and 12th graders aiming for a 5 on the BC exam, students who completed AP Calc AB and want to extend to BC, and students applying to STEM-heavy colleges where AP Calc BC is the expected math credential. Tae's longest-running students reach BC after multi-year prep through Pre-Calc and AB.
