AP Physics C 2025 Format
This section of our AP Physics C exam guide gives in-depth coverage on its recently updated format. Here’s a breakdown –
- The Physics C exam is administered in two separate exam sessions for AP Physics C : Mechanics and AP Physics C : Electricity and Magnetism.
- Both these exams have two sections each – an Multiple Choice Questions (MCQs) section and a Free-Response Questions (FRQs) section.
- The number of options in MCQs has been reduced from 5 to 4.
- Each section contributes 50% to the overall score of each exam.
- Students are permitted to use a four-function, scientific or graphing calculator throughout the entire exam.
- Students are also provided with a reference sheet that contains physics equations and constants.
- The number of questions in each section and the duration of the exam has been updated as per the AP Physics C Exam Guide 2025. Details are in the next section.
AP Physics C Exam Structure
This part of the AP Physics C exam guide will walk you through the key changes in the AP Physics exam, emphasizing the new hybrid testing approach and the scoring system to help you prepare accordingly. Both AP Physics C : Mechanics and AP Physics C : Electricity and Magnetism will have a hybrid exam structure, which means that the first section will be answered online and the second section is to be hand-written on the provided paper booklets. Each of these exams will have a total duration of 90 minutes. Here’s a summary for each of the exams –
| Sections | Number of Questions | Time Allotted | Scoring Scale | Mode of Exam |
|---|---|---|---|---|
| Section I – Multiple Choice Questions | 40 | 80 minutes | 1-5 | Hybrid |
| Section II – Free-Response Questions | 4 | 100 minutes | 1-5 | Hybrid |
The multiple choice questions (MCQs) section as per the includes individual or set of questions based on a single diagram, data set or a graph. The free-response questions are scored on the quality of solutions presented based on the efficacy of the claim, evidence or reasoning provided along with the answers. The FRQ section as per the AP Physics C Exam Guide 2025 will include questions based on four fundamentals –
- Mathematical routines

How to Study for AP Physics C Exams
Every student aspiring to study physics in future should consider working through an AP Physics C exam guide thoroughly to stay ahead in the game. Listed below are few of our tips to do so –
Work on your Foundational Knowledge
AP Physics C is calculus-based. Solidify your concepts and clear your basics on derivatives, integrals, application of derivatives and application of integrals. In Physics, do not simply memorise formulae, understand the principles behind them.
Use Reliable Resources
The most crucial AP Physics C exam guide is the official AP Physics C Course and Exam Description or the CED. The CED lists all the topics under every unit along with their learning objectives and details of the subsequent exams. Besides that, it’s important to refer to textbooks and their end of the chapter questions and exercises, online tutorials and references and other review books like Barron’s, Princeton Review among others.
Practice Practice Practice
Work on a variety of problems like conceptual questions, quantitative questions and free-response questions and work on understanding underlying ideas, calculations, algebraic problems etc. Focus on derivatives that require deriving equations from fundamental principles for the FRQs. Analyse your mistakes and identify your weaker points.
Strategise your Preparation as per the Latest Hybrid Format
Practice on the Bluebook app and get used to the new hybrid format. Get used to the interface and tools. Practice to make a smooth transition from answering the MCQs online to viewing the FRQs on the screen and writing them on paper. Practice presentation of your answers clearly in a more organised fashion. Learn using the calculator provided in the Bluebook app.
Time Management
Manage your time well. You have 40 questions to answer in 80 minutes in the first section. Try not to spend more than 2 min per question in the MCQ section. If you get stuck, move on and come back to the question later. For Section II, you have four questions to be solved in 100 minutes. Allot 25 minutes per question to pace yourself well.
Important AP Physics C FRQ Tips
Another important aspect of the AP Physics C exam guide 2025 stresses on preparing for FRQs using practice content on the College Board website. It’s crucial to strategically practise questions based on the four main ideas covered in the FRQs from 2025 –
- Mathematical Routines – It involves a lot of practice in deriving symbolic expressions and performing multi-step calculations.
- Translation Between Representations – This involves developing the skills to understand and convert data between graphs, equations, diagrams and verbal descriptions
- Experimental Design and Analysis – This skill enables you to design experiments, identify variables, analyse given data and the ability to interpret results.
- Qualitative and Quantitative Analysis – This is the ability to connect qualitative descriptions to quantitative relationships like ability to move between seamlessly describing a physical phenomenon in words to representing it in a mathematical equation or graph, and vice versa.
AP Physics C Multiple Choice Strategies
- There are 40 MCQs to be answered in 80 minutes. Pace yourself accordingly.
- Pay attention to keywords while reading the questions to comprehend them well.
- Assess the concepts involved in the question before starting any calculations.
- Ensure that the unit mentioned in the chosen answer aligns with the units mentioned in the question.
- Use the elimination method to rule out the obvious and incorrect answers or when you are in doubt regarding a question.
- Familiarise yourself with equation sheets earlier to avoid wasting time during the exam.
- Listen to your instincts. They are often right. Edit an answer only if you find a definitive error in your reasoning.
- Use the practice content on the College Board’s website to practice the latest format of question style, difficulty level and time pressure.
AP Physics C vs AP Physics 1 – What’s Right for You?
We are often asked whether a student should choose AP Physics C or AP Physics 1. Both these courses are challenging but they differ significantly in their mathematical approach –
- While there is a prerequisite of calculus in AP Physics C, it is important to be proficient in algebra and trigonometry for AP Physics 1.
- AP Physics C covers a lesser range of topics, but they are taught in depth and AP Physics 1 covers a broader range of introductory physics topics with less complexity.
- AP Physics C is highly regarded by universities, especially for STEM majors. AP Physics 1, though valuable as well, may not give as much college credit or placement for STEM majors.
In a nutshell, choose AP Physics C if you are strong in Mathematics and calculus and plan to major in Engineering, Physics, Chemistry, Computer Science or a related Physical Science field and choose AP Physics 1 if you are planning to major in Biology, General Science or Medicals.
