AP (Advanced Placement) exam registration happens through My AP, the College Board's online portal, and runs in the fall of the year you plan to sit the exam. Most schools set an internal deadline sometime in October or early November so their AP coordinator can submit orders before the College Board's cut-off on November 13, 2026. Miss that and you're either paying a USD 40 late fee or waiting until next year.
The steps are pretty simple if you're taking an AP class at a normal high school. They get more complicated if you're homeschooled, self-studying, or trying to sit an exam your school doesn't offer. This guide walks through each situation, whether you're registering for AP Biology, AP Psychology or any other AP subject.
If you're taking an AP class at your school
This is the most common path and it's straightforward. In September, your AP teacher will give you a class join code. You use that code in My AP to enroll in your class section, which links you to the College Board's system and lets the exam get ordered on your behalf.
Once you're joined to a class section, a Register button appears. Clicking it flags to your AP coordinator that you want to sit the exam. The coordinator then places the actual order with the College Board and collects payment from you or your family through the school. You don't pay the College Board directly.
Your teacher will usually walk the class through this in the first week or two of school. If they don't, ask. It's not something to leave until later, because the deadlines your school sets tend to be earlier than you'd expect.
Sign up in September even if you're not sure yet whether you'll sit the exam. Your AP coordinator can remove you from the order later, and until you've committed with your name on the list, they can't reserve you a spot. Late fees kick in after November 13.
Key registration dates for the 2026-27 year
The College Board's national deadline for ordering exams without a late fee is November 13, 2026. Orders placed between November 14, 2026 and March 12, 2027 are charged an additional USD 40 per exam. Cognito's guide to AP exam costs covers the base fee, late fees, and available fee reductions.
Your school will set its own internal deadline earlier than that so the AP coordinator has time to compile and submit the order. Common internal deadlines fall in the last week of October or the first week of November. Check with your AP coordinator in September so you know your school's date.
| Date | What happens |
|---|---|
| September 2026 | AP teachers hand out class join codes; students enroll in class sections in My AP |
| Late Oct / early Nov 2026 | Most schools set their internal registration deadline |
| November 13, 2026 | College Board's national deadline; no late fee if ordered by this date |
| November 14, 2026 – March 12, 2027 | Late-order window; extra USD 40 per exam |
| Early May 2027 | AP exams administered (specific dates published by College Board in the fall) |
If you're homeschooled or self-studying
Homeschool and self-study students can sit AP exams, but the process starts with finding a school that will take you as an external candidate. Not every school does. Some limit exams to their own students; some accept externals but cap the number.
Start in August or September. Use the College Board's AP Course Ledger or contact your local public and private high schools directly and ask two questions: Do you administer AP exams to external candidates, and do you have room for the exam(s) I want to sit? If the answer to both is yes, you'll work with that school's AP coordinator to get enrolled in a class section on My AP, register for the specific exams, and pay the fees (often with a small administration fee on top of the College Board's USD 99 base for domestic students).
Homeschool students who qualify for fee reductions can still receive them, but the test center school has to flag eligibility when ordering. Bring documentation with you when you first meet with the coordinator.

If you want to take an AP your school doesn't offer
This is a common situation. Your school offers AP US History but not AP Comparative Government, and you want to sit the exam anyway. You have two options.
First, ask your school's AP coordinator whether they'll administer the exam even without a class. Many will, especially if you're already an AP student in other subjects. If they agree, you'll register through your school's regular process but without a class section to join, so the coordinator sets you up manually in My AP.
Second, if your school won't administer it, treat yourself as an external candidate at a different school (see the homeschool section above). Contact neighboring schools, find one that takes externals, and register there. This is more common than you'd think, and coordinators at bigger schools often expect a handful of external candidates each year.
Work through these in September to make sure you're set up before your school's deadline.
- Create or sign into your College Board account
- Get the class join code from each AP teacher and enroll in the section on My AP
- Confirm you can see a Register button next to each class
- If you qualify, ask your coordinator to apply the College Board fee reduction
- Find out your school's internal registration deadline and pay by then
- Check exam dates and any scheduling conflicts if you have two exams on the same day
- If you're homeschooled or self-studying, contact a test center school early
Common registration mistakes
Assuming registration happens automatically because you're in the class. It doesn't. You still have to click Register in My AP and your coordinator still has to submit the order. Being enrolled in the class isn't enough.
Missing the school's internal deadline because you were looking at the College Board's public one. Schools cut off earlier so they have time to submit the order. Their date is your date.
Leaving payment to the last minute. Many schools won't submit your order until they've received payment or a fee reduction confirmation. If you drag your feet, you can end up in the late-order window even if you registered on time.
Forgetting about scheduling conflicts. If two of your AP exams fall on the same day and time, the College Board has a late-testing window for the second one, but you have to work through your coordinator to request it. Check the exam schedule in the fall, not the spring.
Self-study students who don't secure a test center by December. By January, most schools with capacity have already committed to their list. You need to be sorted before winter break, not after.
After you've registered
Once you're registered, most of what you'll need to do is on you: Study, sit the exam in May, and wait for scores in early July. Your AP coordinator will send instructions about exam day (what to bring, where to report, when to arrive) closer to the date.
Use the time between registration and May well. Cognito's AP Biology, AP Psychology and other AP course notes are organized by the College Board's Course and Exam Description so you can revise the exact topics the exam tests, and each subject has past-style practice questions with mark schemes to work through as you get closer to May.
One last thing: Registering doesn't mean you're locked in forever. If you decide before your school's internal deadline that you'd rather not sit an exam, tell your coordinator so they can remove it from the order. After November 13, cancelling costs the USD 40 cancellation fee, and after March 12 the College Board treats you as sitting the exam regardless.
