AP Physics C: E&M Tutor — Calculus-Based Electricity and Magnetism

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 Physics C: Electricity and Magnetism

  • Electrostatics: Coulomb's law in integral form, electric field calculations by integration
  • Gauss's law: applying Gauss's law to point charges, lines, planes, spheres, and cylinders
  • Electric potential: potential from charge distributions, equipotential surfaces, energy of a charge configuration
  • Capacitance and dielectrics: parallel-plate, spherical, cylindrical capacitors; energy stored
  • Current and resistance: microscopic Ohm's law, resistivity, RC circuit analysis with differential equations
  • Magnetic fields: Biot-Savart law, Ampere's law applied to wires, loops, and solenoids
  • Electromagnetic induction: Faraday's law, motional EMF, inductors, LR circuit analysis
  • Maxwell's equations: the four equations and their physical meaning

Who AP Physics C: E&M tutoring at Palo Alto Mentor is for

Best fit: 12th graders who completed AP Physics C: Mechanics, students concurrently enrolled in or having completed AP Calculus BC, and students applying to top engineering or physics programs. This is one of the most demanding AP exams and typically taken last.

How sessions work

  • 100% online via Zoom plus a shared digital whiteboard
  • Weekly cadence — 1-hour standard, 90-minute during exam season
  • Personalized progress tracking: Tae logs weak topics across the year
  • Mock exams in the spring with detailed scoring breakdown
  • Direct text and email access between sessions for time-sensitive questions
