AP Physics C: Mechanics exam-day guide
AP Physics C: Mechanics · Prepare for the day ahead.
Your checklist
Photo ID (needs_review)
Confirm with your school or test center whether a current photo ID is required for admission. If it is required, place it in your bag the night before and keep it with you at check-in.
Exact reporting time and location (needs_review)
Confirm the reporting time, room or building, and whether your administration uses the digital Bluebook format or paper. Write the details down and plan to arrive early; arrival rules vary by test center, so confirm with the provider.
Approved calculator
Bring a College Board-approved scientific or graphing calculator with working batteries. AP Physics C: Mechanics allows calculator use throughout the exam, so know where the key functions are before test day.
Backup calculator if permitted (needs_review)
Some test centers allow a backup calculator and some do not. Confirm the local policy with your school or test center before bringing a second device.
No. 2 pencils, erasers, and pens
Bring several sharpened No. 2 pencils and a good eraser. If your exam is digital, bring a pen or pencil for any permitted scratch work and confirm what materials the test center supplies.
Scratch-paper policy (needs_review)
Do not assume you may bring your own scratch paper. Confirm whether scratch paper is provided and how much is allowed; use only materials the proctor gives you.
Simple watch, not a smartwatch
A basic watch can help you pace the 45-minute multiple-choice section and the 45-minute free-response section. Leave smartwatches and any device with communication or storage features at home or stored as directed.
Snack and water for the break
Bring a quiet snack and water for the scheduled break if your test center permits them. Keep them stored away during testing and follow proctor instructions about where food and drink may be kept.
Charged school-issued device if digital (needs_review)
If your school administers the exam in Bluebook, confirm whether you use a school-issued device and whether you must bring it charged. Practice the equation editor and the on-screen directions before exam day.
Formula-sheet familiarity
A formula sheet is provided during the exam, but you should know its layout and common equations so you do not waste time searching. Review units, constants, and common derivations in the final days.
Sleep and morning logistics
Set two alarms, prepare clothes and materials the night before, and eat a normal breakfast. Avoid last-minute cramming that leaves you tired during a 90-minute exam.
Plan the day
Confirm your reporting time, location, device format, and ID requirements with your school or test center. Take one timed multiple-choice section and one timed free-response set under exam conditions, then review errors by topic rather than rereading everything.
Practice with the provided formula sheet and your calculator. Focus on unit consistency, vector components, energy and momentum bookkeeping, rotational analogs, and showing clear setup on free-response questions. Keep sessions moderate and protect your sleep schedule.
Pack your ID if required, approved calculator, pencils, erasers, watch, snack, and water. Charge any permitted device and confirm the morning transportation plan. Do a light review of formula-sheet locations and common mistakes, then stop studying early enough to sleep.
Eat breakfast, arrive early per the confirmed reporting time, and use the restroom before check-in. Keep your phone off and stored as directed; do not bring unauthorized notes, smartwatches, or other electronic devices into the testing room.
During check-in, follow proctor instructions, show required ID if asked, and confirm that your calculator is permitted. Listen carefully to directions about timing, breaks, scratch paper, and how to submit or collect materials.
Budget about 45 minutes for 35 multiple-choice questions. Work steadily, mark uncertain items, and return to them if time allows. There is no penalty for guessing, so leave no blank answers unless the exam directions say otherwise.
Use the 45 minutes for three free-response questions strategically. Read all parts first, show symbolic setup before substituting numbers, include units and reasonable significant figures, and label diagrams. If you get stuck, move on and return.
Watch the clock but do not panic-check it. Use the provided formula sheet efficiently, keep calculator work organized, and use scratch paper to avoid algebra slips. On the digital exam, confirm that your typed or entered answers appear where intended before moving on.
Rules to check
Bring only permitted materials. Phones, smartwatches, and other electronic devices must be off and stored as directed; unauthorized devices can lead to score cancellation.
Follow all check-in and ID requirements. If you are unsure whether a photo ID is required, confirm with your school or test center before exam day rather than assuming.
Calculators are permitted throughout AP Physics C: Mechanics, but you are responsible for bringing an approved calculator with working batteries. Confirm any backup-calculator policy locally.
A formula sheet is provided during the exam. Do not bring unauthorized notes, equation sheets, or reference materials unless the proctor explicitly permits them.
Take breaks only when the proctor schedules them. Do not leave the testing room or building unless instructed, and return promptly when the break ends.
Maintain academic integrity: do not look at another student's work, share answers, or discuss exam content during or after the test in ways that violate College Board rules.
Scoring: the multiple-choice section and free-response section are equally weighted, and there is no penalty for incorrect multiple-choice answers. The final score is reported on the 1-5 AP scale.
If a rule or procedure is unclear, ask the proctor before the section begins. Do not invent a workaround; confirm with the provider or test center.
