AP Exam Schedule 2027: Every Date, Time and Late-Testing Slot

Quick answer: The 2027 AP exams run from Monday 3 May to Friday 14 May 2027, in two weeks of morning and afternoon sessions. Late-testing exams run from Monday 17 May to Friday 21 May 2027. Most US schools start at 8 a.m. and 12 p.m. local time. Schools in other time zones start at different local times, so students in India, the UAE, Singapore and Hong Kong should check their own start times below.

If you search for the AP exam schedule, you want three things: the date of each exam, the time it starts where you live, and what to do if two exams clash. This guide gives you all three. Every date comes from College Board’s own 2027 pages, which we checked in November 2026.

We also added what the official pages leave out: which exams share a slot, which days are the heaviest, and how to plan your revision around them. Educifly’s tutors teach AP Math, Physics and Chemistry one-on-one, and the same scheduling questions come up every spring, so we built the answers into one place.

The 2027 AP exam dates at a glance

The 2027 AP exams take place on 3–7 May and 10–14 May, with late testing on 17–21 May. Here are the key dates in one table.

College Board has not named a score release day yet. It says July. We will cover score timing in a separate guide when the date is announced.

Week 1 schedule: Monday 3 May to Friday 7 May 2027

Week 1 has 21 exam slots, and Thursday 6 May is the busiest day with five exams. Session 1 is the morning session and Session 2 is the afternoon session.

Two things to notice. Physics C: Mechanics is on the very first morning. And Physics 1 and Physics C: Electricity and Magnetism sit in the same afternoon slot on Wednesday 5 May, so one student cannot take both in the regular window.

Week 2 schedule: Monday 10 May to Friday 14 May 2027

Week 2 has 18 exam slots, and Friday 14 May is the busiest day with five exams.

Calculus AB and Calculus BC are both on Monday 10 May in Session 1. That means you sit one or the other, never both, in the regular window. If you are choosing between them, read our guide to AP Calculus AB vs BC before you register.

The AP exam schedule by subject (A to Z)

If you only care about one exam, find it here. This list sorts the same 39 slots by name.

Once you know your date, the next question is what the paper looks like. Our guide to the AP Physics 1 exam shows the format, timing and scoring for one of the busiest science exams.

What time do AP exams start?

Most US schools start AP exams at 8 a.m. for Session 1 and 12 p.m. for Session 2, in their own local time. This covers all schools in the lower 48 states, Hawaii and Washington, D.C.

Schools in other places can start at different local times. College Board does this so that secure exam content does not travel across time zones. It publishes a table of start times by UTC offset. Here is what it lists for May 2027.

College Board lists the offsets, not the country names. The “common places” column is our own reading of standard time zones. Always confirm with your school, because a few locations have their own special arrangements.

Three rules worth knowing:

• Exams can begin up to one hour after the official start time. Do not panic if your coordinator starts you a little late.

• Early testing is not allowed. Testing at any time other than the published times is not allowed either.

• Your AP coordinator tells you when and where to report. College Board also has a school start-time lookup tool on AP Central.

What these times mean for students in India

A 6:30 a.m. start is early. The Session 2 start at 10:30 a.m. is easier. Students with Session 1 exams should practise getting up and doing a full paper at 6:30 a.m. for two weeks before the exam. This is simple, free and often forgotten.

What these times mean for students in the UAE

An 11 a.m. start for Session 1 and 3 p.m. for Session 2 means a long day when you have two exams. Plan a proper meal and a break in between. Practise a full paper at the real time of day, not at your usual study time.

What these times mean for students in Singapore and Hong Kong

A 9 a.m. and 1 p.m. start is close to a normal school day. The main risk is two exams in one day with a short gap. Pack food and water, and keep the break away from your notes.

The late-testing schedule: 17 to 21 May 2027

Late testing runs from Monday 17 May to Friday 21 May 2027, and it uses different exam papers from the regular dates. College Board says late-testing exams are alternate versions, which protects exam security.

Who can use late testing?

College Board says late testing is for students who cannot test during the first two weeks of May, or who have a scheduling conflict. Your school’s AP coordinator orders the late-testing exams for you. You cannot sign yourself up.

Some rules apply:

• Students at a school who late test must take the alternate exams on the published late-testing dates and times.

• Testing early is never allowed.

• In most cases there is no extra fee for the late-testing period. Confirm this with your coordinator, because your school may set its own charges.

• Schools outside the US, including US territories and Canada, must order late-testing exams by 4 May 2027. Schools in the US have until 14 May 2027.

Late testing after a clash

Late testing is how most students fix a clash. If you want both Physics 1 and Physics C: Electricity and Magnetism, you sit one on the regular date and the other in the late-testing week. Check the late table above. Physics C: Electricity and Magnetism is on Thursday 20 May in Session 1, and Physics 1 is on Wednesday 19 May in Session 1.

Ask your coordinator early. The earlier a school knows, the easier it is to arrange.

Which exams share a slot? The clash table

A clash happens when two exams are in the same session on the same day, so you cannot sit both on the regular dates. The same-slot pairs below are the ones students ask about most.

Physics 1 and Physics C: Electricity and Magnetism is the clash science students ask about most. Calculus AB and BC is really one decision, not two. Physics 2 and French on 6 May, and Physics C: Mechanics and Human Geography on 3 May, also share a session.

Back-to-back days and heavy days

A heavy day is any day with three or more of your exams. Most students have two or three exams in the whole two weeks, so a heavy day is rare. But some combinations are hard even without a clash.

Here are the pairs students with a maths and science focus ask about most.

If you have two exams in one day, plan your rest. Sleep matters more than one extra hour of last-minute revision. Eat a proper meal at the break. Keep your phone away from notes.

How to plan revision around your dates

Work back from your exam date. A simple plan:

1. Twelve weeks out: finish the last unit in class or on your own.

2. Eight weeks out: do one timed paper every week for each subject.

3. Four weeks out: fix your weakest unit using the official unit weights.

4. Two weeks out: drop to one paper per subject per week. Practise at the real start time of your time zone.

5. Last three days: light review only. Check your calculator, your Bluebook app and your ID.

For 2027, twelve weeks before 3 May is early February. That is why we say demand for this topic peaks from January to May.

What changes for the 2027 schedule?

The 2027 list includes Cybersecurity, Networking (pilot schools only) and Business with Personal Finance, plus AP Precalculus. Older schedule guides from before 2025 will not list them, so check the year on any guide you read.

Two other points:

• AP Seminar, AP Research and several portfolio-based courses have submission deadlines before the exams. Most are due on 30 April 2027, 11:59 p.m. ET. AP Art and Design is due on 7 May 2027.

• AP World Languages and Cultures has a new Personalized Project Reference with a 30 April 2027 deadline.

If you take one of these, put the April date in your calendar now. A late portfolio is a problem no study plan can fix.

How much do AP exams cost in 2027?

An AP exam costs $99 at a school in the US, its territories, Canada or a DoDEA school, and $129 at a school outside those places. Fees at authorised test centres outside the US vary.

The late order fee applies to exams ordered from 14 November 2026 to 12 March 2027. It does not apply to courses that start after 13 November 2026, or to students who transfer into the school. Your school may also charge more than the listed fee to cover proctoring and admin. You cannot pay on the College Board website. Your school submits the fees.

The first deadline to remember is 13 November 2026. After that date, ordering an exam costs $40 extra, and cancelling an ordered exam costs $40.

How to check your exact schedule

You do not need to guess. Follow these five steps.

1. Find your exams in the A-to-Z table above and note the date and session.

2. Ask your AP coordinator for your start time. Check it against the UTC offset table.

3. Compare your dates against the clash table. If two exams share a slot, tell your coordinator now.

4. Ask whether your school offers late testing, and when your coordinator needs your answer.

5. Put every date, plus the April portfolio dates, into your calendar with a reminder two weeks before.

Does the date change if I live outside the US?

No. The exam day is the same for every student, but the local clock time changes. An exam on Wednesday 5 May is on Wednesday 5 May for a student in Mumbai, Dubai, Singapore and New York. What moves is the start time.

This is why the offset table matters. A Session 1 exam that starts at 8 a.m. in a US school starts at 6:30 a.m. on the +05:30 offset. Session 2 starts at 10:30 a.m. there. College Board sets these times so that students in different time zones are not sitting the same paper at hours that let questions travel from one place to another.

Students at international schools also have a second planning job. Your school may close for a local holiday, a board exam or a school event in May. Ask your coordinator for the school calendar for 3–21 May. Local exam clashes, such as an IB or IGCSE paper, are not fixed by College Board, so the school has to plan around them. If you take AP exams alongside IB or IGCSE exams, our IB vs AP guide explains how the two systems differ.

The 2027 AP exam order by subject area

Exams are spread across the two weeks by subject area, so your own dates depend on your course mix. This table groups the schedule so you can see where each family of subjects falls.

Two patterns matter for planning. All the big science exams fall in week 1, apart from Environmental Science. All the maths exams fall in week 2, apart from Cybersecurity. A student who takes both a science and a maths course will usually finish their science exams before they sit the maths ones, which helps the second half of revision.

A month-by-month countdown to the 2027 exams

The best AP plan starts in November, six months before the first exam. Here is a calendar that works for most students.

This is a good list to print and put on a wall. Most missed deadlines happen because a date sat in an email and not in a calendar.

Questions every family should ask the AP coordinator

Your AP coordinator is the person who holds the final answers for your school. College Board sets the dates, but your school decides the building, the room, the report time and many small rules. Ask these questions in December, not in April.

• What is my exact start time for each exam, and does it match the College Board table for our time zone?

• Is every exam I plan to take already ordered, and what is the school’s own payment deadline?

• Do I have a clash? If yes, which exam moves to late testing, and by what date must I confirm?

• Is there an extra charge for late testing at our school?

• Where do I report, and what should I bring?

• If I am ill on the day, what is the school’s process?

Write the answers down and keep them with your exam dates. A short list like this removes most of the stress that builds up in the last two weeks.

Common mistakes with the AP exam schedule

Most schedule problems come from guessing, not from the exams themselves. These are the mistakes we see most.

• Using an old schedule. Dates change every year. A guide from 2025 or 2026 will show the wrong days for 2027.

• Mixing up local time and your own time zone. Session 1 and Session 2 are not the same clock time everywhere.

• Forgetting the portfolio deadline. Computer Science Principles, Seminar and Research tasks are due on 30 April, before the exam week starts.

• Waiting until April to report a clash. Late-testing orders and seats take time to arrange.

• Planning revision around the wrong exam. If your hardest exam is first, your revision plan should end with that exam, not with the last one on your list.

• Not practising at the real start time. A paper that feels easy at 4 p.m. can feel hard at 6:30 a.m.

AP exam schedule 2027: frequently asked questions

When are the 2027 AP exams?

The 2027 AP exams take place from Monday 3 May to Friday 7 May and from Monday 10 May to Friday 14 May 2027. Each day has a morning session (Session 1) and an afternoon session (Session 2). Late-testing exams run from Monday 17 May to Friday 21 May 2027.

What time do AP exams start?

Most US schools start Session 1 at 8 a.m. and Session 2 at 12 p.m. local time. Schools in other time zones use different local times. For May 2027, College Board lists 6:30 a.m. and 10:30 a.m. for the +05:30 offset, 11:00 a.m. and 3:00 p.m. for +04:00, and 9:00 a.m. and 1:00 p.m. for +08:00. Exams can start up to one hour after the official time.

What time do AP exams start in India, the UAE and Singapore?

On College Board’s table, India’s offset (+05:30) starts at 6:30 a.m. and 10:30 a.m. The UAE’s offset (+04:00) starts at 11:00 a.m. and 3:00 p.m. Singapore and Hong Kong’s offset (+08:00) starts at 9:00 a.m. and 1:00 p.m. The table lists offsets, not countries, so confirm with your school.

What are the AP exam late-testing dates for 2027?

Late testing runs from Monday 17 May to Friday 21 May 2027. Each day has two sessions, and the exams are alternate versions of the regular papers. Your AP coordinator orders late-testing exams for you and tells you when and where to report.

Can I take two AP exams on the same day?

Yes, if they are in different sessions. For example, Physics 2 is in Session 1 and Chemistry is in Session 2 on Thursday 6 May 2027. You cannot take two exams that share the same session on the same day. If you want both, one moves to late testing.

Which AP exams clash in 2027?

Exams clash when they share a session. Common examples are Physics 1 and Physics C: Electricity and Magnetism on 5 May (Session 2), and Calculus AB and Calculus BC on 10 May (Session 1). Tell your AP coordinator as early as you can so they can arrange late testing for one exam.

Can I take AP exams early or at a different time?

No. College Board says early testing, or testing at any time other than the published times, is not allowed under any circumstances. The only route to a different date is the late-testing period for students who cannot test on the regular dates or who have a clash.

When is the deadline to register for AP exams in 2027?

Schools must place their orders by 13 November 2026, 11:59 p.m. ET, to avoid a late fee. After that, exams ordered up to 12 March 2027 cost an extra $40 each. Your school handles registration, so ask your AP coordinator what internal deadline they set, which is often earlier.

How much do AP exams cost in 2027?

An AP exam costs $99 at schools in the US, its territories, Canada and DoDEA schools. It costs $129 at schools elsewhere. Students with significant financial need can get $37 off per exam. A cancelled or unused exam after 13 November 2026 costs $40.

When do AP scores come out in 2027?

College Board says AP scores are released in July 2027. It has not published a specific day yet. We will update our score guide as soon as the date is announced.

Do I need to study differently for the morning and afternoon sessions?

Your body clock matters more than the exam. Practise full papers at your real start time for the last two weeks. If you start at 6:30 a.m., that means early mornings. If your exam is at 3 p.m., practise in the afternoon. This one habit helps more students than any extra revision hour.

Dates and fees in this guide come from College Board’s 2027 AP pages and were checked in November 2026. Schedules can change, so confirm your own dates and start times with your school’s AP coordinator.
