AP Exam Day: What to Bring and What to Leave Home

Here’s the core packing list for every AP exam: several sharpened No. 2 wooden pencils with erasers, black or dark-blue pens, a non-smart watch, a valid photo ID (if testing at a school you don’t attend), and up to two approved calculators if your subject allows them. For digital and hybrid exams, add your charged Bluebook device and charger (and know your College Board login — a saved password won’t work). Leave home: phones, smartwatches, all wearables, notes, mechanical pencils, and your own scratch paper — a prohibited item can mean a canceled score. Here’s the complete, format-by-format breakdown.

The core kit every AP exam needs

Regardless of subject or format, a handful of items form the foundation of every AP exam bag — get these right and you’ve covered the essentials. This is the universal kit.

Every student, whatever the subject, needs the same core items. Sharpened No. 2 pencils — wooden, with working erasers, and bring several (mechanical pencils are not allowed on paper portions). Pens with black or dark-blue ink — for free-response sections and booklet covers; no red ink, no erasable ink. A watch that isn’t a smartwatch — an analog or basic digital watch is genuinely useful since not every room has a visible clock, and it must not beep, have an alarm, or access the internet. A valid photo ID — government-issued or current-year school-issued — is required if you’re testing at a school you don’t normally attend (and always for external testers); confirm whether you need it. If your name on your ID doesn’t match your registration, sort that with your coordinator before exam morning. This core kit applies to every format; the additions below depend on whether your exam is digital, hybrid, or a special format. For confirming which format yours is, see our guide on whether AP exams are digital.

Extra items for digital and hybrid exams

Since most AP exams now run through Bluebook, the digital-specific items are essential for the majority of students — and forgetting them is a real exam-day risk. Format determines these additions.

If your exam is fully digital or hybrid (most subjects now), you need several things beyond the core kit. A fully charged testing device with the Bluebook app already installed — capable of holding roughly a four-hour charge — plus its charger or a portable battery, since an outlet isn’t guaranteed. Critically, you must know your College Board account login to sign in to Bluebook on exam day: a saved password won’t work, so memorize or securely note your credentials. Bring pens or pencils for the school-provided scratch paper even on fully digital exams. For hybrid exams specifically, bring two No. 2 pencils or pens for the paper free-response booklet you’ll write in. If you’re testing on a tablet or iPad, an external keyboard is required for fully digital exams (recommended for hybrid); an external mouse is optional. Run the Bluebook device check in advance to confirm your device meets requirements. The distinctions by format are summarized below — but the through-line is: charged device, charger, known login, and something to write with.

Calculators: when you need one and which are allowed

Calculators cause more exam-day confusion than any other item, because the rules are entirely subject-specific — so it’s worth being precise. Only some exams, only approved models.

Calculators are permitted only on certain AP exams — mainly math and science subjects — and prohibited on others entirely. For a calculator-allowed exam, you may bring up to two approved calculators, which is genuinely wise: if one fails or runs out of battery mid-exam, you have a backup. Two important nuances: first, only approved models are allowed — the College Board maintains a specific approved-graphing-calculator list and bans models with typewriter-style (QWERTY) keypads, stylus input, or wireless capability, and proctors check calculators before the exam. Second, for many digital exams a built-in Desmos calculator is available in Bluebook, though you may still bring an approved handheld; note that on some exams (like Calculus and Precalculus) the calculator is only available/permitted on certain parts. Because approval lists and per-subject policies are specific and updated regularly, check the current calculator policy for your exact subject on the College Board’s site before exam day — don’t assume last year’s rules or a friend’s different subject. If your subject doesn’t permit a calculator, don’t bring one to your seat. The safe move is to verify your subject’s policy and bring a familiar, approved, working model (with a backup) if allowed.

What’s prohibited (and why it matters so much)

This is the section that actually protects your score, because the penalty for a banned item is severe and often surprises students — so read it carefully. Prohibited means dismissal-level serious.

Being caught with a prohibited item during testing or breaks — even accidentally — can lead to dismissal from the exam, confiscation of the device, cancellation of your score, and no retest. That severity is why this list matters more than any other. Banned items include: phones, smartwatches, fitness trackers, smart glasses, and wearable technology of any kind; laptops or tablets other than your testing device, portable listening/recording devices, cameras, separate timers, and anything that accesses the internet; electronic writing instruments like stylus pens and Apple Pencil; books, notes, dictionaries, highlighters, correction fluid; mechanical pencils, No. 3 or colored pencils, protractors, compasses; and your own scratch paper (the proctor provides it). Hats and brimmed caps generally aren’t allowed either (religious/medical head coverings are permitted if they don’t obscure your face). The clean way to hold all this is the bring/leave split below — when in doubt about an item, leave it out and confirm with your coordinator.

Food, water, and breaks

Sustenance is allowed — just not where students often assume — so it’s worth knowing the rule to keep your energy up without breaking policy. Snacks are for breaks, not your desk.

Food and drink, including bottled water, aren’t allowed inside the exam room at your seat, unless you have a College Board–approved accommodation. However, you can typically bring snacks and water for the breaks, stored in a designated area outside or away from the testing room rather than on your desk. Since there are breaks between exam sections, having a snack and drink for those breaks is a smart way to maintain energy and focus across a multi-hour exam — just access them in the permitted area during the break, not at your seat during testing. Follow your school’s specific instructions on where items go. A practical tip: pack a simple, non-messy snack with some protein and complex carbs, plus water, in your bag for the break, and leave it wherever the proctor directs. This keeps you fueled through a long morning without any risk of a food-or-drink violation at your desk. Hand sanitizer is generally allowed but must be placed under the desk, not on it.

When to arrive

Timing your arrival well is the final logistical piece, and cutting it close is a needless risk on a high-stakes morning. Early is the whole strategy.

Plan to arrive early — commonly about 30 to 45 minutes before your reporting time. Check-in takes time, testing is often in a different room than your usual classroom, and you’ll need to store prohibited items and complete the sign-in process (including Bluebook check-in for digital exams). Arriving early gives you a buffer for parking, finding the room, and settling without a rushed, adrenaline-spiking scramble. Late arrivals can face complications, and some schools may not admit students who arrive very late, so erring early genuinely protects you. Crucially, confirm your exact reporting time and location with your AP coordinator rather than assuming — your local start time is set within the national window, so it’s specific to your school. Knowing precisely when and where to be, and arriving with margin, turns exam morning from frantic to composed. For how the daily schedule and start-time windows work, see our guide on what AP exams are today.

The night-before routine

Everything above comes together in a simple night-before ritual that removes morning decisions when you need your focus for the exam itself. Pack once, calmly, the evening before.

Done the night before, exam morning becomes simple: grab the bag by the door, arrive early, check in, and focus on the exam. The packing ritual removes cognitive load from a morning when you need your working memory for the test itself. And remember — the perfect bag doesn’t earn the score; content preparation does. Tracking your practice results tells you where you actually stand: running mock exams through the AP score calculator, or the subject-specific tools, projects your 1–5 so your energy goes where it matters most.
