The MCAT takes about 7 hours 30 minutes of seated time, and check-in comes on top of that, so plan on roughly 8 hours at the test center. Arrive at least 30 minutes before your start time with an unexpired government photo ID whose name exactly matches your registration. Everything else, including food, goes in a locker you can reach only on breaks.
Enter your start time below for a minute-by-minute schedule, then tick off the checklist the night before. Every rule here comes from the AAMC's MCAT test day pages and The MCAT Essentials for Testing Year 2027, checked November 13, 2026.
With every optional part taken, the MCAT runs 447 minutes (7 h 27 min) from the certification screen to the end of the survey, so an 8:00 a.m. start finishes around 3:27 p.m. That's 6 h 15 min of testing for 230 questions, plus 50 minutes of optional breaks and a few short screens.
MCAT test-day timeline
Enter the start time from your MCAT confirmation and untick anything you plan to skip. Every break is optional; skipping one doesn't add time to the next section.

Times assume your exam starts on the minute of your appointment. Pearson checks examinees in one at a time, so your own start can be a little later and everything shifts with it. The 30-minute arrival is the AAMC's minimum; check-in time isn't counted in seated time.

Work through it in three passes: the night before, the morning of, and once you're at the center. The list at the bottom covers what stays out of the testing room.

What you can't bring into the testing room
Bring your ID, plus food, water and any medication for the locker. Only your ID and eyeglasses go into the testing room with you; the center supplies the rest. The AAMC's list of items allowed in the testing room is short on purpose, and the Essentials say no other items are permitted without prior approval.
| Item | Where it goes | Notes |
|---|---|---|
| MCAT-accepted ID | On your desk | It must stay visible on the desk the whole exam. |
| Eyeglasses | Testing room | Subject to visual and physical inspection. |
| Food, water, medication | Locker | You can take these out during scheduled breaks only. |
| Phone and small electronics | Sealed bag, then storage | The bag stays sealed until staff open it after the exam. The AAMC suggests leaving your phone at home or in your car. |
| Layered indoor clothing | Wear it | Sweaters and hoodies are fine; coats and jackets are not. You can't take a layer off at your seat. |
| Medical devices or items | Needs approval | Request it through the AAMC accommodations process well before test day. |
Pack the locker bag as if you can't buy anything all day, because you can't: you may not leave the test center floor or building, and outside food can't be delivered. If you need an item for a medical condition, such as food at your desk or an insulin pump, the route is an accommodations request to the AAMC in advance, not a conversation at the front desk.
Your ID must be government-issued, unexpired, intact, in English, with a photo and a printed expiration date, and its first and last names must exactly match your MCAT registration in the same order. Middle names don't need to match. If your ID doesn't match, you can't test, you get no refund, and the appointment counts toward your limits (AAMC valid ID page).
| Accepted (if it meets every rule) | Not accepted |
|---|---|
| State driver's license | Paper IDs or ID application receipts |
| Passport or passport card | Virtual or digital IDs |
| Permanent resident card (green card) | School IDs and employee IDs |
| Employment Authorization Document | IDs with extension stickers or renewal paperwork |
| Consular ID card | Birth certificates, Social Security cards |
| Canada health card (Ontario and British Columbia only), Canadian aviation card | Credit cards, library cards, Veterans ID (VIC) |
Check-in has five steps: agree to the candidate rules, show your ID (which may be scanned), give a digital signature, have your palms scanned, and have a passport-style photo taken. The order can vary slightly (AAMC check-in rules).
Staff check examinees in and seat them one at a time, so your exam may start a few minutes after your appointment time. Every time you enter or leave the testing room, including after each break, you show your ID, scan your palms, pat yourself down, turn your pockets inside out and are scanned with an infrared and metal-detection wand. When you sit down, the exam starts immediately with the test-day certification statement; refusing to accept it ends the exam.
You get a noteboard booklet, a fine-point marker, earplugs and a storage key. During the two science sections you also have an on-screen periodic table. There's no calculator and no equation sheet.
The MCAT has three optional scheduled breaks: 10 minutes after Chem/Phys, 30 minutes after CARS and 10 minutes after Bio/Biochem. You track the time yourself, and going over doesn't earn you extra time anywhere. The Essentials and the AAMC's break page set these rules:
Treat each break as a timed routine: restroom, a snack and water, a minute away from the screen, then back with time to spare for check-in. These are practical habits, not AAMC rules, and they work best if you rehearse them in full-length practice.
After the last section, you get one 3-minute screen to score or void the exam. The choice is final, voids still count toward your testing limits, and if you don't choose in time the exam is scored. To void, you must select "I wish to VOID my MCAT exam" yourself; telling the administrator isn't enough (Essentials, Scoring or Voiding Your Exam).
Decide your rule before test day, when you're calm. Voiding makes sense mainly when something specific went wrong, such as a disruption or illness, rather than because a section felt hard, which is common and hard to judge from inside the exam. A voided attempt isn't refunded, and the AAMC's limits are three attempts in a testing year, four over two consecutive years and seven in a lifetime. If you're not shown the void question, ask the administrator to file a report before you leave and submit a Test Center Concern.
Collect your belongings, hand over your sealed device bag to be opened, show your ID again, and take your completion confirmation letter, which records your score-or-void decision. Keep it for your records.
