The AP Precalculus exam runs 3 hours and tests your ability to work with functions, build models, and explain mathematical reasoning across four units. Knowing the format, calculator rules, and question types before exam day is the fastest way to turn preparation into points.
Use the topic guides below to break down each section of the exam, then check your score estimate with the score calculator.
AP Precalculus tests four units: polynomial and rational functions, exponential and logarithmic functions, trigonometric and polar functions, and functions involving parameters, vectors, and matrices. Every question, whether multiple choice or free response, asks you to work with functions analytically, graphically, numerically, or verbally.
42 questions, 105 minutes, 62.5% of your score. Part A has 29 questions in 65 minutes with no calculator. Part B has 13 questions in 40 minutes with a graphing calculator. Questions pull from all four units and ask you to interpret graphs, evaluate functions, and reason about models.
4 questions, 60 minutes, 37.5% of your score. FRQs 1 and 2 are calculator-required (35 minutes total, 6 points each). FRQs 3 and 4 are no-calculator (35 minutes total, 6 points each). Each question has labeled parts, and you earn points part by part.
A graphing calculator is required for Part B of each section. On no-calculator parts, all work must be exact and algebraic. On calculator parts, use your calculator to evaluate, graph, and find intersection points, but always show the setup that justifies your answer.
Every question on the AP Precalculus exam is ultimately about functions: their behavior, their representations, and their use in modeling real-world contexts. Whether you are solving a logarithmic equation, fitting a sinusoidal model to a tide table, or interpreting a piecewise graph, the exam is asking you to reason about how outputs change with inputs. Build that habit of thinking in functions and the format becomes predictable.
Full breakdown of the 40-question MCQ section: format, pacing plans, calculator strategy for Part B, and what each part tests. Start here if you want to understand how the biggest scoring section is structured.
Covers FRQ 1 (Function Concepts) and FRQ 2 (Modeling a Non-Periodic Context). Includes scoring breakdown, what each part typically asks, and a worked example showing how to use your calculator and still show justification.
Covers FRQ 3 (Modeling a Periodic Context) and FRQ 4 (Symbolic Manipulations). Explains sinusoidal model construction, exact algebraic solving, and the step-by-step work format required when no calculator is allowed.
Looks at what makes the exam challenging, where students typically lose points, and a two-week study path. Useful for calibrating how much time to spend on each section before exam day.
Section I is the largest point source on the exam at 62.5% of your total score. Part A (no calculator) rewards algebraic fluency and graph interpretation. Part B (graphing calculator) rewards efficient calculator use and numerical reasoning. Pacing matters: 65 minutes for 28 questions is about 2 minutes 51 seconds per question in Part A, and 40 minutes for 12 questions is about 3 minutes 20 seconds in Part B.
| Part | Questions | Time | Calculator | Score weight |
|---|---|---|---|---|
| Part A | 28 | 80 min | No | 43.75% |
| Part B | 12 | 40 min | Yes | 18.75% |
Section II has four questions worth 6 points each, totaling 37.5% of your score. FRQs 1 and 2 are in Part A with a graphing calculator. FRQ 1 (Function Concepts) tests composition, inverses, and function behavior across representations. FRQ 2 (Modeling a Non-Periodic Context) asks you to build and interpret an exponential or other non-periodic model. FRQs 3 and 4 are in Part B without a calculator. FRQ 3 (Modeling a Periodic Context) typically involves a sinusoidal function built from a real-world scenario. FRQ 4 (Symbolic Manipulations) is pure algebra: solving and rewriting exponential, logarithmic, and trigonometric expressions exactly.
| FRQ | Type | Calculator | Points |
|---|---|---|---|
| FRQ 1 | Function Concepts | Yes | 6 |
| FRQ 2 | Modeling Non-Periodic | Yes | 6 |
| FRQ 3 | Modeling Periodic | No | 6 |
| FRQ 4 | Symbolic Manipulations | No | 6 |
Each FRQ is scored out of 6 points across labeled parts (a, b, c, etc.). Points are awarded part by part, so a wrong answer in part (a) does not automatically cost you points in part (b) if you set up part (b) correctly using your earlier answer. Always show your reasoning. On no-calculator questions, unsupported answers earn no credit even if the final value is correct.
| Section | Weight | Points available |
|---|---|---|
| Section I (MCQ) | 62.5% | 42 questions |
| Section II (FRQ) | 37.5% | 24 raw points (4 x 6) |
FRQs 3 and 4 award points for each step of your algebraic process, not just the final answer. Writing only the answer, even a correct one, earns zero points. Show every inverse operation, every substitution, and every simplification step.
On calculator-required FRQs, you must show what you entered and why. Stating a decimal answer without writing the function or equation you evaluated is not sufficient for full credit. Write the setup, then the result, then the interpretation.
In f(x) = A sin(Bx + C) + D, the period is 2pi divided by B, not B itself. A common error is setting B equal to the period from the problem context instead of computing B = 2pi divided by the period. Double-check this step every time you build a sinusoidal model.
The exam alternates calculator access between parts. Using a calculator during Part A of either section is a testing violation, and forgetting to use it strategically during Part B wastes time. Know which part you are in before you start each set of questions.
Each FRQ is 6 points, but some parts within an FRQ are worth more than others. Read through all parts of a question before starting so you can allocate your 15 minutes per FRQ toward the highest-value parts first if you are running short on time.
Because the MCQ section is 62.5% of your total score, your pacing strategy in Section I has more impact than any single FRQ. Practicing timed MCQ sets and building a skip-and-return habit for hard questions is one of the highest-leverage things you can do before exam day.
Symbolic Manipulations (FRQ 4) pulls from exponential, logarithmic, and trigonometric equation solving, which spans Units 2 and 3. Students who review exact solving techniques for all three function families before the exam are better positioned to earn full credit on every part of FRQ 4.
FRQ 3 is the dedicated sinusoidal modeling question, but MCQ questions in Section I also test period, amplitude, midline, and phase shift. Understanding sinusoidal function construction pays off in both sections of the exam.
