The AP Physics suite is notoriously one of the most challenging sets of exams offered by the College Board. For students aiming at top-tier STEM programs (Engineering, Computer Science, Pre-Med), taking AP Physics is almost a mandatory rite of passage. But with four different physics courses available, students are often left wondering: which one do I actually need to take?
In recent years, the College Board has significantly restructured the AP Physics curriculum to better align with university expectations. Understanding the distinction between algebra-based and calculus-based physics is the first step in mapping out your high school schedule.
The Algebra-Based Track: Physics 1 & 2
AP Physics 1: Mechanics
The Entry-Level Beast
- Focuses entirely on Newtonian mechanics (motion, forces, work, energy, momentum).
- Requires strong Algebra II and Geometry skills.
- Has traditionally had one of the lowest '5' rates of any AP exam (often ~8-10%).
- Heavily emphasizes conceptual understanding and written justifications over math.
AP Physics 2: Modern & E&M
The Continuation
- Covers completely different topics: fluids, thermodynamics, electricity, magnetism, optics, and modern physics.
- Physics 1 is highly recommended as a prerequisite.
- Excellent choice for future biology and pre-med students who need general physics in college.
The Calculus-Based Track: Physics C
AP Physics C is the track intended for future engineers, computer scientists, and physics majors. It uses Calculus (both derivatives and integrals) to solve complex, real-world problems. The 'C' track is split into two distinct half-year courses, though many schools teach them back-to-back in a single year.
Physics C: Mechanics
Covers the same topical ground as Physics 1 (motion, forces, energy) but applies Calculus to solve them. For example, instead of assuming constant acceleration, you will use integrals to find the velocity of an object with changing acceleration.
Physics C: Electricity & Magnetism
Notoriously the hardest AP exam. It covers electrostatics, circuits, magnetic fields, and electromagnetism. It requires a solid grasp of Multivariable Calculus concepts (like surface integrals) to truly understand Gauss's and Ampere's Laws.
The Core Prerequisite
You MUST be taking AP Calculus AB or BC concurrently with Physics C. You cannot survive Physics C without knowing how to take a derivative.

| Equation Sheets | Updated to be more comprehensive. | Updated; students no longer need to memorize obscure constants. |
- Taking Physics 1 expecting it to be 'Easy Math' Students often assume Physics 1 will be easy because it only uses Algebra. In reality, the College Board removed the complex math so they could test your pure conceptual logic. You have to explain WHY things happen in paragraphs, not just solve for x.
- Taking Physics C without Prior Physics Jumping straight into AP Physics C without taking a regular/honors physics class (or AP Physics 1) first is incredibly risky. You are trying to learn complex physics concepts AND apply calculus to them simultaneously.

Our academic advisors can review your math background and help you select the exact AP Physics course that engineering and medical schools want to see.
College Credit Implications
Universities are extremely strict about how they award credit for Physics because it is foundational to STEM degrees.
“Engineering schools DO NOT accept AP Physics 1 or 2 for major credit. They require Calculus-based physics.”

Check ProfileWhich Course Should YOU Take?
Your decision should be based entirely on your intended college major and your current math level.
The Future Engineer
You want to study Mechanical, Aerospace, or Electrical Engineering. You must take AP Physics C: Mechanics and E&M. Ideally, take Physics 1 in 11th grade, and Physics C in 12th grade alongside AP Calculus BC.
The Future Doctor
You want to go to Med School or study Biology. Take AP Physics 1 and 2. Medical schools require general (algebra-based) physics. You do not need the stress of Physics C.
The Ivy League Humanities Applicant
You want to study English at Yale, but want to show academic rigor. Take AP Physics 1. It demonstrates that you can handle hard sciences without forcing you to learn Calculus-based electromagnetism.
Taking Physics C when you want to study Biology is a classic mistake. It damages your GPA, causes unnecessary stress, and the engineering-level credit doesn't even help your major requirements.

FAQs: AP Physics
Can I take AP Physics C: E&M without taking Mechanics?
Technically yes, but practically no. E&M builds heavily on the force and energy concepts established in Mechanics. You will be completely lost if you attempt E&M first.
Why is the pass rate for AP Physics 1 so low?
Because it's often the first AP science class students take, and they expect it to be purely math. Physics 1 requires you to write paragraph-length conceptual explanations, which catches many students off guard.
Do I need to take the AP Physics 1 exam if I'm taking Physics C next year?
No. If you are definitely taking Physics C, colleges will only care about your Physics C score. You can take the Physics 1 class for the foundational knowledge and skip the exam.
Is AP Physics harder than AP Chemistry?
It depends on how your brain works. Physics is heavily visual and conceptual (forces, vectors). Chemistry requires massive amounts of memorization and abstract atomic rules. Most students find Physics C harder than AP Chem due to the calculus requirement.
How long are the new 2026 Physics C exams?
The College Board has expanded both Physics C exams to full 3-hour tests (instead of 90 minutes). This gives you more time per question and a standardized 4-question FRQ section.
