AP Statistics Study Plan for the May 2027 Exam

Quick answer

A good AP Statistics study plan starts with the facts from College Board: the exam is on Tuesday, May 11, 2027, in the afternoon session (Session 2), and it is fully digital in the Bluebook app. You get 42 multiple-choice questions in 1 hour 30 minutes and 4 free-response questions in another 1 hour 30 minutes, each section worth 50% of your score.

The course was revised for 2026-27, so the units and the free-response section look different from what older guides describe. If you start now and work through the five units in order, you have time for one full pass, a review round and practice exams in April and May.

Below: what changed, the exam format in one table, the five units with their weightings, a month-by-month plan, how to practice FRQs, and what the formula sheet and calculator rules mean for you.

What changed for 2026-27

College Board revised AP Statistics for the 2026-27 school year "to align with current introductory college statistics courses." The exam is now fully digital in Bluebook, the course has five units, and Section II has four free-response questions.

Here is what that means in practice:

• Five units, new names. The Course and Exam Description (CED) effective Fall 2026 organizes the course into five units, from exploring one-variable data to regression analysis. If your review book lists a different set of units, it was probably written before the revision.
• Four FRQs. Section II now has four questions in 1 hour 30 minutes. Guides that describe a different number of free-response questions or a separate investigative task are out of date.
• Digital answers. You type both multiple-choice and free-response answers in Bluebook, and College Board publishes guidelines for entering statistical notation on a regular keyboard.

The unit order matters too. In the CED, inference for proportions (Unit 3) comes before inference for means (Unit 4), and regression is the last unit.

AP Statistics exam format at a glance

The exam has two sections of equal weight and equal length. This table comes straight from the AP Statistics exam page on AP Central.

	Section I: Multiple choice	Section II: Free response
Questions	42	4
Time	1 hour 30 minutes	1 hour 30 minutes
Weight	50%	50%
Format	single questions or sets based on a shared prompt	Q1: Practices 1 and 2. Q2: Practices 3 and 4. Q3: inference (hypothesis test or confidence interval). Q4: Practices 2, 3 and 4
Where	Bluebook	Bluebook

The four practices are Formulate Questions, Collect Data, Analyze Data and Interpret Results. In the multiple-choice section, the CED gives them these approximate weightings: Practice 1 at 5 to 10%, Practice 2 at 20 to 30%, Practice 3 at 25 to 35% and Practice 4 at 25 to 35%.

That last number is worth a second look. Interpreting results in context is about a quarter to a third of the multiple-choice section, so "the answer is 0.032" is never the end of a question.

Units and what to master

The CED lists five units, and all five are assessed in the multiple-choice section with these approximate weightings. Use the weightings to decide where extra review time goes.

Unit	MCQ weighting	What to master
Unit 1: Exploring One-Variable Data and Collecting Data	20 to 30%	describing distributions in context, sampling methods, experimental design
Unit 2: Probability, Random Variables, and Probability Distributions	15 to 25%	probability rules, random variables, the distributions your teacher covers
Unit 3: Inference for Categorical Data: Proportions	15 to 25%	confidence intervals and significance tests for proportions, checking conditions
Unit 4: Inference for Quantitative Data: Means	10 to 20%	intervals and tests for means, choosing the right procedure
Unit 5: Regression Analysis	10 to 20%	describing relationships, interpreting slope and residuals

Unit 1 has the highest weighting range, so don't treat it as the easy warm-up you can skip in review.

Month-by-month plan, November to May

Follow your class through the units until March, review weak units in April and do full timed practice in May. Here is one way to split the months, based on the CED unit order.

Month	Focus	Weekly habit
November	Unit 1 review, Unit 2 with your class	one past FRQ, written in full
December	Unit 2	15 minutes of mixed multiple choice
January	Unit 3	one inference FRQ with all four steps
February	Unit 3 and Unit 4	compare a proportions problem with a means problem
March	Unit 4 and Unit 5	one regression interpretation in context
April	review of your two weakest units	a full Section II in 1 hour 30 minutes
May	full practice exam, then light review	rest the day before May 11

Your class may move at a different speed. That's fine. Keep the weekly habits even if the unit column shifts by a few weeks.

If you also take AP Calculus AB or AP Biology this year, the same structure works there too: see our AP Calculus AB study plan and AP Biology study plan.

How to practice FRQs

Practice FRQs by writing complete answers in context and then scoring them with the official scoring guidelines. AP Central publishes past free-response questions with scoring information, so you can see what earns credit.

Three habits do most of the work:

• Always use context. "The mean is 12.4" is incomplete. "The mean commute time in this sample is 12.4 minutes" is an answer.
• State and check conditions. For inference, name the conditions and show why they are met with the numbers from the problem.
• Answer the actual question. End with a sentence that responds directly to what was asked, in the language of the problem.

Here is a practice prompt we wrote ourselves (it is not from a College Board exam):

A school surveys a random sample of 120 students and finds that 78 say they get less than 8 hours of sleep on school nights. Construct and interpret a 95% confidence interval for the proportion of all students at the school who get less than 8 hours of sleep.

A strong answer names the procedure (one-sample z interval for a proportion), checks conditions (random sample, 120 is less than 10% of the student body if the school is large enough, and at least 10 successes and 10 failures: 78 and 42), computes the interval (p-hat = 0.65, roughly 0.565 to 0.735), and interprets it in context: "We are 95% confident that the true proportion of students at this school who get less than 8 hours of sleep on school nights is between about 0.565 and 0.735."

Since the exam is digital, practice typing at least some FRQs. College Board's digital response guidelines show how to enter statistical notation, and Bluebook offers test previews you can try.

Formula sheet and calculator tips

You get formulas and tables for both sections, and a graphing calculator is permitted. The CED says students are expected to use a graphing calculator with statistical capabilities.

• Learn the formula sheet before May. College Board says reference materials are available in Bluebook in the test preview and on exam day. Look at them now so you know what is there and what you still need to understand.
• Know what the formulas mean. The sheet gives you a standard error formula, not when to use it. Practice choosing the procedure.
• Use your own calculator all year. Check it against the AP calculator policy list, then use the same one in class, on homework and on practice exams.
• Show the setup, not just the output. On FRQs, write which procedure you used and the key values, not only "calculator says."

Studying with a teacher, a tutor or AI

Your AP teacher is your best resource, because they know your pace and can grade FRQs against the rubric. A private tutor or an AI tutor helps when you need more practice than class time allows, and for most students an AI tutor can replace a private tutor, though not for everyone.

Astra AI is our product, so keep that in mind here. You can snap a photo of a problem or ask a question, and the tutor explains it step by step, at your level, and asks you questions back. Upload your notes or old tests, and Astra AI builds a study plan with quizzes, flashcards, podcasts and mock exams from that material.

One honest weakness: AI can make mistakes, and in statistics a wrong condition or a misread question can look perfectly confident. Check important answers against your notes, the CED and the official scoring guidelines. If you need someone to keep you accountable every week, a person may suit you better.

You can start free, no card required. Astra AI Plus unlocks unlimited tutoring, mock exams and podcasts for less per month than a single hour of private tutoring.
