ExploreAbout this exam
AP Precalculus is a College Board Advanced Placement course and exam intended for students who want college-level credit or placement in precalculus-level mathematics before moving on to calculus. The exam measures understanding of the mathematical content in units 1–3 and the ability to apply skills such as algebraically manipulating functions, equations, and expressions; translating mathematical information between representations; and communicating with precise language and rationales. Questions draw on general functions, polynomial and rational functions, exponential and logarithmic functions, and trigonometric and polar functions, presented graphically, numerically, analytically, and verbally, with real-world modeling contexts. The exam is hybrid digital: multiple-choice questions and free-response questions appear in the Bluebook app, while free-response answers are handwritten in paper booklets. A graphing calculator is required for parts of the exam and permitted throughout, with radian mode required where graphing calculators are used. Preparation should combine steady work through the course framework, familiarity with the Bluebook testing app and the sample free-response booklet, and practice explaining reasoning clearly, since free-response questions are each worth 6 points and include both calculator and no-calculator parts.
What you'll study
About AP Precalculus preparation
How long is the AP Precalculus exam, and how is it split?
The exam runs 2 hours 55 minutes across two sections. Section I has 42 multiple-choice questions in 1 hour 45 minutes and counts for 62.5% of the score. Section II has four free-response questions in 1 hour 10 minutes and counts for 37.5%.
Is a calculator allowed on the AP Precalculus exam?
Calculators are permitted for the exam, and a graphing calculator is required for parts of it. Section I Part A and Section II Part B do not permit calculators; Section I Part B and Section II Part A require a graphing calculator, in radian mode, for some or all questions.
How does the hybrid digital format work?
You complete multiple-choice questions and view free-response questions in the Bluebook testing app. You then handwrite your free-response answers in paper exam booklets, which are returned for scoring. Practice with the Bluebook test previews and the sample free-response booklet before exam day.
What do the four free-response questions cover?
Question 1 is Function Concepts and Question 2 is Modeling a Non-Periodic Context; both are in the graphing-calculator part. Question 3 is Modeling a Periodic Context and Question 4 is Symbolic Manipulations; both are in the no-calculator part. Each question is worth 6 points.
How hard is the AP Precalculus exam?
Difficulty is subjective, but the exam rewards fluency across four function families and the ability to move between graphical, numerical, analytical, and verbal representations. The no-calculator portions put a premium on algebraic manipulation and exact values, so weakness there is the most common source of lost points.
Can I retake the AP Precalculus exam?
The provided sources do not state a retake policy for this exam, so this cannot be confirmed here. Ask your AP coordinator about registering for a later administration and about any associated deadlines or fees.
What score do I need, and what does it cost?
The provided sources do not list a passing score or an exam fee for AP Precalculus, so neither can be confirmed here. Check with your AP coordinator and the college that would grant credit, since credit and placement policies vary by institution.
In what order should I study the units?
Follow the course sequence: general functions first, then polynomial and rational functions, then exponential and logarithmic functions, then trigonometric and polar functions. Build representation-translation skills early, because later units assume comfort with function notation, transformations, and rates of change.
What are common failure modes on the free response?
Answers that give a number without justification, omit units or context, or fail to state a conclusion lose points even when the arithmetic is right. On no-calculator questions, students often stall on symbolic manipulation. Practice writing complete, precise rationales and showing setup before computing.
When is the exam offered?
The listed exam date is Tuesday, May 11, 2027, Session 1. Your AP coordinator will tell you when and where the exam will be administered, so confirm logistics with them rather than relying on general dates.
