Are you ready for Precalculus?
A free Precalculus readiness check shows which advanced-function skills are solid, which ones need repair, and where to start in the Precalculus: Advanced Functions course.
The useful question is not "Am I good at math?" It is which Precalculus building blocks are ready: function notation, domain and range, transformations, inverses, polynomial and rational behavior, exponentials, logarithms, sequences, vectors, and early limit thinking.

What you should already be comfortable with before Precalculus
Precalculus assumes a solid Algebra 2 base and the core of Trigonometry. Before starting, a student should be comfortable with:
- From Algebra 2 — factoring, solving quadratic and polynomial equations, function notation and graphs, rational expressions, and exponentials and logarithms.
- From Trigonometry — radians and the unit circle, the six trig functions, basic identities, and right-triangle relationships.
Shaky on any of these? The check tells you which to shore up first — or review Algebra 2 readiness and the Trigonometry course.
What the readiness check looks for
Precalculus pulls together several earlier strands of math. A student can be strong in one area and still need a short repair plan in another. The check samples the skills that most often decide whether the course feels organized or overwhelming.
- Function foundations - notation, inputs and outputs, domain and range, graph features, and average rate of change.
- Transformations and composition - shifts, reflections, stretches, function operations, and one function inside another.
- Inverse functions - one-to-one behavior, the horizontal line test, inverse rules, and inverse graphs.
- Polynomial and rational functions - degree, end behavior, zeros, multiplicity, division, restrictions, holes, and asymptotes.
- Exponential and logarithmic functions - growth, decay, log meaning, log rules, and equations.
- Discrete and bridge topics - sequences, series, parametric equations, polar coordinates, vectors, difference quotients, and informal limits.
How ClearMath uses your result
- Take the Precalculus placement check. It is a routing tool, not a grade.
- Read the gap report. Missed questions map to exact Precalculus lessons instead of vague topic labels.
- Follow the 4-week repair plan. The plan groups work into function foundations, inverses and polynomials, rational/log topics, and final bridge skills.
- Practice with worked solutions. Each lesson has checked practice, a quiz, and review pathways for missed work.
Find the first lesson to repair. The check routes you into the actual Precalculus course sequence.

Algebra II
Review here if factoring, function notation, radicals, rational expressions, exponentials, or logarithms feel shaky.
Algebra II placement checkTrigonometry
Review here if radians, the unit circle, trig graphs, identities, equations, or triangle applications need a stronger base.
Review the Trigonometry courseWhat we do and do not promise
The check gives a useful starting point, a gap report, and a 4-week plan tied to the ClearMath course. It does not claim AP Precalculus alignment, school approval, official College Board alignment, guaranteed Calculus readiness, or guaranteed test-score improvement.
Frequently asked questions
How do I know if I'm ready for Precalculus?
You are ready to begin when the main function families and graph features are workable enough to build on. The check helps separate solid areas from topics that need repair first.
What does the Precalculus readiness check cover?
It covers functions, domain/range, transformations, composition, inverses, polynomial and rational functions, exponentials, logarithms, sequences, parametric and polar basics, vectors, difference quotients, and informal limits.
Is it free?
Yes. The readiness check, gap report, 4-week plan, lessons, worked examples, practice, and quizzes are free to use.
What happens after the check?
You get a recommended starting point and a 4-week repair plan that links back to specific lessons inside Precalculus: Advanced Functions.
