AP Physics 1 vs AP Physics C: Which Should You Take?

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.

AP Physics 1, AP Physics 2, AP Physics C: Mechanics, and AP Physics C: E&M are four different exams covering overlapping content at different math levels. Here's how to choose.

Quick comparison

AP Physics 1 AP Physics 2 AP Physics C: Mech AP Physics C: E&M
Math required Algebra + trig Algebra + trig Calculus Calculus
Content Mechanics, waves Thermo, E&M, optics, modern Mechanics (calculus-based) E&M (calculus-based)
Exam length 3h 3h 1h 30m 1h 30m
Typical grade 10th–11th 11th–12th 11th–12th 12th
5-rate (recent year) ~10% ~16% ~26% ~33%
College credit Algebra-based mechanics Algebra-based E&M Calc-based mechanics Calc-based E&M

The honest take: AP Physics 1 is the hardest of the four

AP Physics 1 has the lowest 5-rate of any AP exam at around 10%. It's not that the content is harder — it's that the exam is taken by 10th and 11th graders, many of whom are taking AP Physics 1 as their first physics class ever, often without strong algebra/trig fluency. The Physics C exams have higher 5-rates because they're taken by older, more selected students.

How to decide

Take AP Physics 1 if:

  • It's the only physics AP offered at your school
  • You haven't taken calculus yet
  • You're a sophomore or junior taking your first physics class

Take AP Physics 2 if:

  • You completed AP Physics 1 and want to continue
  • You want algebra-based E&M, thermo, and optics for college credit
  • Your school offers Physics 1 and 2 as a two-year sequence

Take AP Physics C: Mechanics if:

  • You're concurrently in AP Calculus (or have completed it)
  • You're planning to major in engineering, physics, or a math-heavy STEM field
  • Your school offers Physics C (most don't)

Take AP Physics C: E&M if:

  • You completed (or are completing) AP Physics C: Mechanics
  • You're comfortable with calculus, including integration techniques
  • You want one of the most rigorous AP credentials for top engineering programs

What's worth knowing about the C exams

The two AP Physics C exams (Mechanics and E&M) are typically taken on the same day, back-to-back — one in the morning, one in the afternoon. You can take just one or both. They're shorter than the Physics 1 and 2 exams (90 minutes each) but more math-intensive.

What Tae recommends

For our students applying to engineering programs, AP Physics C: Mechanics (plus AP Calc) is the most valuable physics credential. Students who haven't taken calculus yet should take AP Physics 1 to build the conceptual foundation, then move to Physics C in 12th grade if calculus is also in their plan.
