Honors Pre-Calculus Tutor — Direct AP Calc Prep

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 Honors Pre-Calculus

  • Functions: domain, range, composition, inverses, transformations
  • Polynomial and rational functions: deeper than Algebra II, including limits at infinity
  • Exponential and logarithmic functions: modeling, growth and decay, change of base
  • Trigonometry: the full unit circle from memory, all identities, trig graphing, polar coordinates
  • Conic sections: ellipses, hyperbolas, parabolas, parametric representations
  • Sequences, series, and induction: arithmetic and geometric, sigma notation, intro to limits
  • Intro to limits: the bridge concept into AP Calc — getting comfortable before AB starts
  • Vectors and matrices: 2D and 3D vectors, dot product, applications

Who Honors Pre-Calc tutoring at Palo Alto Mentor is for

Best fit: 10th and 11th graders heading into AP Calculus AB or BC, students whose Pre-Calc class is moving too fast, and ambitious students who want to start AP Calc already comfortable with the prerequisites.
