What the exam covers
The multiple-choice section samples Units 1–3; Unit 4 is taught in the course but not tested. Each unit page has its key ideas, common mistakes and a full unit test.
Average rate of change is a slope: The average rate of change of f on [a, b] is (f(b) − f(a)) ÷ (b − a), the slope of the secant line. Linear functions have a constant rate of change; quadratics have rates of change that change at a constant rate, so their second differences over equal steps are constant.
Linear adds, exponential multiplies: Over equal input steps a linear function adds the same amount and an exponential function multiplies by the same ratio. In f(x) = a·bˣ, a is the initial value and b is the growth (b > 1) or decay (0 < b < 1) factor; growth of r% per step means b = 1 + r.
The unit circle defines sine and cosine: For an angle θ in standard position, the point where its terminal ray meets the unit circle is (cos θ, sin θ), and tan θ = sin θ ÷ cos θ is the slope of the ray. Learn the values at multiples of π/6 and π/4.
Practice exam FAQs
How is this practice exam like the real AP Precalculus exam?
It has 42 multiple-choice questions, the number in Section I from May 2027, drawn from Units 1–3 in line with their exam weighting: 15 from Unit 1 (30–40%), 13 from Unit 2 (25–40%) and 14 from Unit 3 (30–35%). The optional timer gives you the real section's 105 minutes (65 for Part A and 40 for Part B).
Do I need a calculator?
No. Every question here can be done without one, like Part A of the real exam. On exam day, Part B (13 questions) needs a graphing calculator, so practise using yours for graphs, intersections and regressions as well.
Where do the questions come from?
They are original StudyCoach questions drawn from our unit test banks, mapped to the College Board's course framework. They are not released College Board questions. If you have already taken our unit tests, some questions will look familiar.
Does it include free-response questions?
This page is the multiple-choice section. Practise the free-response section on our FRQ practice page, which has one original question of each of the four official types, with scoring guides.
Is it good for a final exam or midterm review?
Yes. Because it covers every tested unit, it works as a cumulative review. Use the score by unit to decide which unit tests to retake before your final, midterm or the AP exam.
