Last updated: September 2, 2026

The confirmed 2027 AP Physics exam changes affect AP Physics 1, AP Physics 2, AP Physics C: Mechanics, and AP Physics C: Electricity and Magnetism. Each exam will have 42 multiple-choice questions in 85 minutes, followed by four free-response questions in 95 minutes. The total testing time remains 180 minutes, and each section still contributes 50% of the exam score.

All four exams remain hybrid digital. Students answer multiple-choice questions and read free-response prompts in the Bluebook testing app, but they handwrite their free-response work in a paper booklet. That distinction matters: “digital” does not mean typing physics derivations or drawing graphs on a screen.

This guide separates confirmed College Board changes from features that are staying the same. It also explains the 2026–27 Course and Exam Description clarifications, official testing dates, international start-time rules, calculators, reference materials, and a practical preparation plan.

1. 2027 AP Physics exam changes at a glance

Confirmed 2027 format for all four AP Physics exams
AP Physics course	2027 confirmed change	Multiple-choice format	Free-response format	Exam delivery mode	What students should do differently
AP Physics 1	MCQ count and both section times updated	42 questions, 85 minutes, 50%	4 questions, 95 minutes, 50%	Hybrid digital	Use 42/85 MCQ sets and 4/95 handwritten FRQ sets
AP Physics 2	MCQ count and both section times updated; targeted CED clarification	42 questions, 85 minutes, 50%	4 questions, 95 minutes, 50%	Hybrid digital	Update pacing and review the Fall 2026 clarification
AP Physics C: Mechanics	MCQ count and both section times updated	42 questions, 85 minutes, 50%	4 questions, 95 minutes, 50%	Hybrid digital	Practice faster handwritten derivations within 95 minutes
AP Physics C: Electricity and Magnetism	MCQ count and both section times updated; reference conventions clarified	42 questions, 85 minutes, 50%	4 questions, 95 minutes, 50%	Hybrid digital	Use current conventions and rehearse the revised timing

The numerical change is the same in every row. Compared with the 2026 format, Section I gains two questions and five minutes. Section II keeps four questions but becomes five minutes shorter. Because five minutes move from free response to multiple choice, the combined section time does not change.

What is not changing: the 50% multiple-choice and 50% free-response weighting, the four established free-response task types, calculator access on both sections, the availability of reference information, and the hybrid method of handwriting free-response answers.

2. AP Physics 1: Algebra-Based

The AP Physics 1 exam is scheduled for Wednesday, May 5, 2027, Session 2. Its 42 multiple-choice questions may appear as stand-alone items or as sets built around a shared diagram, experiment, data display, or physical situation. The four free-response questions cover mathematical routines, translation between representations, experimental design and analysis, and qualitative/quantitative translation.

Students should not interpret two extra multiple-choice questions as a major content expansion. The official Fall 2026 clarification document identifies the exam-format adjustment and updates where teachers can find listed resources; it does not announce a new Physics 1 unit. The central preparation issue is pacing. The 2027 average is about 2.02 minutes per MCQ, nearly the same as 80 minutes for 40 questions, so practice should emphasize decisive modeling rather than rushed arithmetic.

3. AP Physics 2: Algebra-Based

AP Physics 2 is scheduled for Thursday, May 6, 2027, Session 1. It uses the same 42/85 and 4/95 structure and the same four free-response categories. Students still need to move among words, equations, diagrams, graphs, and experimental evidence—not merely select formulas.

Physics 2 also has a confirmed 2026–27 content clarification. Essential Knowledge statement 15.7.B.1 now describes radioactive decay as the spontaneous transformation of a nucleus into one or more different nuclei, or to a lower energy level of the same nucleus. The reference-information conventions were also updated. This is a clarification to use with the current CED, not evidence of a broad new curriculum. Students should obtain the current reference sheet through their course or official College Board materials instead of relying on an old saved copy.

4. AP Physics C: Mechanics

AP Physics C: Mechanics is scheduled for Monday, May 3, 2027, Session 1. The calculus-based exam follows the same revised section timing: 42 MCQs in 85 minutes and four FRQs in 95 minutes. Its free-response prompts retain the four science-practice categories used across the redesigned physics exams.

The Fall 2026 clarification document lists the timing and question-count changes but does not announce an additional assessed unit. Preparation should therefore remain rooted in the current Mechanics framework: build models, connect derivatives and integrals to physical quantities, justify sign choices, and present symbolic reasoning clearly. The shorter FRQ section makes it especially important to set up a derivation efficiently before substituting values.

5. AP Physics C: Electricity and Magnetism

AP Physics C: Electricity and Magnetism is scheduled for Wednesday, May 5, 2027, Session 2. It does change in 2027: like the other physics exams, it moves from 40 to 42 MCQs and from 80 to 85 minutes for Section I, while Section II moves from 100 to 95 minutes and remains four questions.

The 2026–27 clarification document also notes updated conventions in the reference information. No sweeping new E&M course framework is announced. Students should continue practicing field, potential, circuit, magnetic, and induction models using the current CED, while checking that symbols and conventions match the current official reference sheet. That is more reliable than memorizing the layout of an older equation sheet.

6. How the hybrid digital workflow works

Sign in and check in: Students use their College Board account credentials on an approved device running Bluebook. The proctor manages the administration at school.
Complete Section I in Bluebook: Multiple-choice prompts and answer choices appear in the app, and responses are entered digitally.
Read Section II on screen: Free-response questions are displayed in Bluebook. Students do not type their solutions into the app.
Write in the paper booklet: The proctor distributes the official booklet. Students handwrite equations, explanations, graphs, and diagrams on paper, following the on-screen and booklet directions.
Submit both parts correctly: Digital responses are submitted through Bluebook, while the paper booklet is collected and returned to the AP Program for scoring.

College Board states that full-length 2027 sample free-response booklets are expected in early 2027. In April, students should also open Bluebook’s Practice and Prepare area and complete the AP test preview. A preview is an untimed interface practice, not a full-length scored AP practice exam.

7. 2026 versus 2027 exam structure

Before-and-after format for every AP Physics exam with a confirmed 2027 update
Exam	Previous format	2027 format	Main student impact
AP Physics 1	40 MCQs / 80 min; 4 FRQs / 100 min	42 MCQs / 85 min; 4 FRQs / 95 min	Two more MCQs and five fewer FRQ minutes
AP Physics 2	40 MCQs / 80 min; 4 FRQs / 100 min	42 MCQs / 85 min; 4 FRQs / 95 min	Same total time, redistributed between sections
AP Physics C: Mechanics	40 MCQs / 80 min; 4 FRQs / 100 min	42 MCQs / 85 min; 4 FRQs / 95 min	Less time for derivations across the FRQ set
AP Physics C: Electricity and Magnetism	40 MCQs / 80 min; 4 FRQs / 100 min	42 MCQs / 85 min; 4 FRQs / 95 min	Revised pacing plus current reference conventions

The table shows why “a longer exam” would be misleading. The exam does not gain net section time. Instead, the balance shifts slightly toward the multiple-choice section. The average MCQ time changes only marginally—from exactly two minutes per question to about two minutes and one second—while the average FRQ allowance falls from 25 minutes to 23 minutes 45 seconds.

8. Calculators, reference sheets, and exam-day materials

For all four AP Physics exams, a four-function, scientific, or graphing calculator is allowed on both sections. Bluebook provides built-in Desmos scientific and graphing calculators, and students may bring up to two permitted handheld calculators. A familiar approved handheld model can be a useful backup, but students cannot share calculators during the exam.

Reference information is provided in print and is also available in Bluebook. Students should not bring their own reference guide. For a hybrid exam, bring two sharpened No. 2 pencils with erasers or pens with black or dark blue ink for the free-response booklet. A ruler or straightedge is permitted for AP Physics; a protractor is not.

If the school requires a student-provided device, it should be fully charged, have the current Bluebook app installed, and include a compatible charging cord or adapter. Phones and personal Chromebooks are not approved testing devices. Students must know their College Board account credentials because Bluebook does not save them for exam-day sign-in. Always follow the testing school’s instructions, since the school decides whether students use personal or school-managed devices.

9. How students should adjust their preparation

Recalibrate MCQ sets: Practice 42-question, 85-minute blocks occasionally. Keep shorter topic sets for learning, but use the official 2027 ratio for final pacing checks.
Protect FRQ setup time: Practice four-question sequences in 95 minutes. Read the task verb, identify the representation required, and outline the model before doing algebra.
Train both media: Read prompts on a screen while writing complete solutions on paper. Make graphs, subscripts, vector notation, and final answers legible.
Use current conventions: Review the Fall 2026 clarification sheet for the course and use the latest official reference information. Avoid treating unofficial equation sheets as authoritative.
Practice the interface early: Complete the Bluebook test preview on the device and with the accessibility tools intended for exam day. Resolve account or device problems before May.
Prepare calculator strategy: Know which calculations are genuinely faster with a calculator and which are clearer symbolically. Verify that any handheld calculator appears on the permitted list.
Use released official FRQs: Older questions remain valuable for concepts and scoring habits, but combine them into four-question, 95-minute sets rather than copying their historical timing.
Run two full simulations: Before exam week, complete at least two 180-minute section simulations and review whether every FRQ shows equations, substitutions, units, and requested reasoning.

10. Suggested 2026–27 study timeline and exam dates

September–November 2026: Learn the course models unit by unit, review the Fall 2026 clarification for the chosen course, and build accurate diagram, graph, and equation habits.
December 2026–January 2027: Mix topics in timed MCQ sets and complete one handwritten FRQ from each of the four task categories.
February–March 2027: Increase to longer mixed sets, score official released FRQs with their published guidelines, and keep an error log organized by modeling, calculation, representation, and explanation.
April 2027: Use the Bluebook AP test preview, inspect the 2027 sample booklet when available, verify the calculator and device, and complete the first full 42/85 plus 4/95 simulation.
Final two weeks: Complete a second full simulation, correct it carefully, then review high-value errors and logistics rather than trying to relearn the entire course.

The four regular exam dates fall in the first week of the May 3–14, 2027 AP exam window. Mechanics comes first on May 3; Physics 1 and C: E&M share Session 2 on May 5; Physics 2 follows in Session 1 on May 6. Students registered for both Physics 1 and C: E&M should contact their AP coordinator because the two exams occupy the same regular-session slot.

“Session 1” and “Session 2” replace the former morning and afternoon labels. Most schools in the lower 48 United States, Hawaii, and Washington, D.C. retain 8:00 a.m. and 12:00 p.m. local starts, but some locations—including international schools—use start times determined by their May UTC offset. For example, the official table lists 9:00 a.m. and 1:00 p.m. at UTC+08:00. Students should confirm the actual arrival and start time with their coordinator instead of assuming a universal local schedule.

11. Frequently asked questions

Is the 2027 AP Physics exam fully digital?

No. All four are hybrid digital AP exams: MCQs are completed in Bluebook, while FRQs are read on screen and answered in a paper booklet.

Will students type their free-response answers?

No. Students view FRQ prompts in Bluebook and handwrite their responses in a paper booklet that is collected for scoring.

Which AP Physics exams are changing in 2027?

All four: AP Physics 1, AP Physics 2, AP Physics C: Mechanics, and AP Physics C: Electricity and Magnetism receive the same section-count and timing update.

Is AP Physics C: E&M changing in 2027?

Yes. It changes to 42 MCQs in 85 minutes and four FRQs in 95 minutes. Separate Fall 2026 clarifications also update reference-information conventions.

Can students use a calculator?

Yes. Four-function, scientific, or graphing calculators are allowed on both sections, and Bluebook includes Desmos scientific and graphing calculators.

Do students need to install Bluebook?

Bluebook must be installed on the approved testing device. The school decides whether it prepares a managed device or requires the student to prepare an allowed personal device.

Are old AP Physics practice exams still useful?

Yes, for content, representations, and scoring practice. Their historical timing may differ, so final simulations should use the confirmed 2027 structure and the current course framework.

When are the 2027 AP Physics exams?

C: Mechanics is May 3, Session 1; Physics 1 and C: E&M are May 5, Session 2; and Physics 2 is May 6, Session 1. Confirm the local start time with the AP coordinator.

12. Final takeaway

The 2027 AP Physics exam changes are precise rather than sweeping: two more MCQs, five more minutes for Section I, and five fewer minutes for the same four FRQs. Every AP Physics exam keeps its hybrid digital workflow, three-hour combined section time, equal section weighting, calculator access, and established free-response categories.

The best response is equally precise. Update timed sets to 42/85 and 4/95, rehearse reading on screen while writing on paper, use the current reference conventions, and verify Bluebook, calculator, date, and local start-time details through official channels. College Board can revise operational guidance, so students and schools should recheck the linked pages as exam day approaches.
