Each FRQ has 4–6 parts. Enter your total raw points (0–6) for each FRQ.
Function modeling task with a real-world context (population, temperature, motion). Calculator allowed. Show setup before using the calculator.
Choose an appropriate function model from data; interpret in context. Calculator allowed for finding regression, zeros, intersections.
Algebraic manipulation: solve equations, identify transformations, simplify expressions. Show all steps — partial credit per step.
Function analysis: domain, range, transformations, intervals of behavior. Communicate reasoning clearly — labels and units matter for partial credit.
How Is the AP Precalculus Exam Scored?
AP Precalculus is a new exam (first administered in May 2024). Its scoring is the standard AP math model: MCQ and FRQ contribute weighted points to a 0–100 composite that maps to 1–5. The MCQ weight is heavier than on AP Calculus AB/BC — about 62.5% vs the 50/50 split on calculus.
The official section weights
| Section | Format | Time | Calculator | Weight |
|---|---|---|---|---|
| I-A · MCQ | 28 questions | 80 min | No | 43.75% |
| I-B · MCQ | 12 questions | 40 min | Yes | 18.75% |
| II-A · FRQ | 2 questions × 6 pts = 12 raw | 30 min | Yes | 18.75% |
| II-B · FRQ | 2 questions × 6 pts = 12 raw | 30 min | No | 18.75% |
The composite formula
MCQ_total is your combined raw score from Part A (28) and Part B (12) = max 40. FRQ_total_raw is your combined raw from Q1 + Q2 + Q3 + Q4 = max 24. The composite is mapped to 1–5 using estimated cutoffs.
Estimated composite-to-AP-score cutoffs
| AP Score | Composite (estimated) | Practical example |
|---|---|---|
| 5 | 65 – 100 | 30/40 MCQ + 18/24 FRQ = ~75 (solid 5) |
| 4 | 50 – 64 | 25/40 MCQ + 14/24 FRQ = ~60 (4) |
| 3 | 35 – 49 | 20/40 MCQ + 9/24 FRQ = ~45 (3) |
| 2 | 22 – 34 | 14/40 MCQ + 6/24 FRQ = ~31 (2) |
| 1 | 0 – 21 | Below the 2 threshold |
AP Precalculus has the most generous AP math curve. A 5 requires only ~65% composite — compared to ~77% on Calc AB and ~70% on Stats. Because the exam is new, cutoffs may shift more than usual year to year.
The AP Precalculus Exam Format in Detail
The exam is a 3-hour hybrid digital test. The MCQ section is delivered through Bluebook on a school-provided device. The FRQ section is handwritten in a paper booklet — same as AP Calculus and AP Statistics. You'll switch between digital and paper during the exam.
Section I — Multiple Choice (40 questions, 120 minutes, 62.5%)
Part A (no calculator): 28 questions in 80 minutes. Roughly 2.9 minutes per question. Tests algebraic manipulation, function properties, identities, exact trigonometric values. The unit circle, factoring, logarithm properties, and trig identities must be memorized.
Part B (calculator): 12 questions in 40 minutes. Roughly 3.3 minutes per question. Tests numerical reasoning, regression, finding zeros of complicated functions, intersections. Calculator efficiency matters — practice finding zeros and intersections quickly with TI-84 or equivalent.
Section II — Free Response (4 questions × 6 raw = 24, 60 minutes, 37.5%)
Each FRQ is worth 6 raw points. Part A is two calculator-active FRQs (~15 minutes each); Part B is two no-calculator FRQs (~15 minutes each). The 4 question types rotate:
- FRQ 1 — Function in Context (calculator): real-world model (population, temperature, finance). Identify type of function from data, interpret in context.
- FRQ 2 — Modeling (calculator): build or evaluate a function model. Often uses regression on the calculator.
- FRQ 3 — Symbolic Manipulation (no calculator): algebraic equations, transformations, identities. Show every step for partial credit.
- FRQ 4 — Function Communication (no calculator): describe function behavior (intervals, transformations, end behavior). Communication is graded — write in complete mathematical sentences.
AP Precalculus Score Distributions
AP Precalculus was first administered in May 2024. The inaugural year saw a strong but cautious curve; 2025 showed measurable improvement as teachers and students gained familiarity with the format. Two years of official data:
| Year | 5 | 4 | 3 | 2 | 1 | 3+ (Pass) | Mean |
|---|---|---|---|---|---|---|---|
| 2025 | 28.1% | 21.0% | 32.0% | 12.0% | 6.9% | ~81% | 3.55 |
| 2024 (inaugural) | 25.9% | 21.0% | 28.0% | 14.0% | 11.1% | ~75% | 3.42 |
What the trend means
Two clear patterns from year-1 to year-2:
- 5-rate up: from 25.9% to 28.1%. Suggests College Board is comfortable maintaining a generous curve.
- 1-rate down: from 11.1% to 6.9%. Pass rate climbed from ~75% to ~81%.
- Mean up: 3.42 → 3.55. Suggests teacher familiarity with the exam is improving outcomes broadly.
If you've completed Algebra 2 and feel solid with functions and trigonometry, a 4 is realistic with focused preparation. A 5 requires consistent practice with both calculator-active and no-calculator problems.
How to Get a 5 on AP Precalculus
A 5 requires ~65/100 composite — the most generous threshold in AP math. The best path is to identify where you lose the most points (often it's the no-calculator MCQ Part A) and target practice there.
⚡ Don't study Unit 4
Unit 4 (Vectors, Matrices, Parametric Functions) is on the course outline but NOT tested on the AP exam. Skipping it saves prep time. Only Units 1–3 (Polynomial/Rational, Exp/Log, Trig/Polar) are tested.
🎯 Unit circle is non-negotiable
Memorize exact values for 0°, 30°, 45°, 60°, 90° and their multiples in all four quadrants. Roughly 6–8 MCQs in Part A (no calculator) test these directly. Drill them until recall is automatic.
🖩 Master 4 calculator tasks
For Part B and FRQ-A, you need calculator fluency in: (1) graphing a function and finding zeros, (2) finding intersections of two functions, (3) computing exponential or logistic regression, (4) numerical integration of a model. Build muscle memory before exam day.
✍️ Show setup before calculator
For calculator FRQs, write the equation or integral before pressing buttons. A calculator answer with no setup loses partial credit. "Show the setup, then use the calculator to evaluate" is the AP-approved phrasing.
📊 FRQ 4 is communication-graded
FRQ 4 (Function Communication) is scored on how clearly you explain. Write complete mathematical sentences. "f is increasing on (−∞, 2)" not just "increasing." Use units in context problems. Communication errors can lose 2–3 points on otherwise correct math.
📚 Use released 2024 + 2025 FRQs
College Board has released 2024 and 2025 free-response questions with scoring guidelines. These are your gold-standard practice. Time yourself (15 min per FRQ) and self-grade with the official rubric.
The 3 AP Precalculus Units Tested
Only Units 1–3 are tested on the AP exam. Unit 4 is technically part of the course curriculum but does not appear on the exam.
| Unit | Topics | Approximate MCQ Weight |
|---|---|---|
| 1 · Polynomial & Rational Functions | Function notation, domain/range, transformations, end behavior, asymptotes, complex zeros, polynomial long division | 30–40% |
| 2 · Exponential & Logarithmic Functions | Exponential models, log properties, solving exp/log equations, inverse functions, logarithmic scales | 27–40% |
| 3 · Trigonometric & Polar Functions | Unit circle, trig functions and their graphs, identities, solving trig equations, polar coordinates and curves | 30–35% |
| 4 · Vectors, Matrices, Parametric (NOT TESTED) | Vectors, matrix operations, parametric equations — taught in many AP courses but skipped on the exam | 0% |
