Brilliant covers math from grade 4 foundations through college-level topics. Its school-math paths include fractions, pre-algebra, Algebra I, geometry, Algebra II, precalculus, and calculus; other courses cover probability, statistics, logic, number theory, contest math, vectors, and matrices. Four grade-banded course groupings run from grades 4–12, while Advanced Math and enrichment courses extend beyond high school. Brilliant’s math curriculum is comprehensive in scope, but it is organized by concept rather than as a one-to-one copy of every school or exam syllabus.

Brilliant math coverage at a glance
What grade levels does Brilliant math cover?
Brilliant’s structured school-math progression begins with grade 4–5 fractions and extends through grade 12 algebra and precalculus topics. It’s most commonly used in grades 5–12, while advanced courses also serve college students and adults.
| Course grouping (by topic) | Approximate grade band | Example courses |
|---|---|---|
| Foundational math | Grades 4–7 | Fractions; Solving Equations; Negative Numbers; Coordinate Plane; Percents; Proportional Reasoning |
| Algebra I topics | Grades 7–9 | Linear Equations; Coordinate Geometry; Linear Relationships; Exponents and Radicals; Visual Algebra |
| Intermediate algebra topics | Grades 8–11 | Introduction to Functions; Linear Systems; Quadratics; Coordinate Transformations; Exponentials and Logarithms |
| Advanced algebra topics | Grades 11–12 | Trigonometric Functions; Polar Coordinate Plane; Complex Numbers; Polynomials; Equations and Curves; Vectors and Matrices |
| Advanced math | Advanced | Calculus; Vectors and Matrices |
The bands overlap because readiness can differ by topic. These groupings describe the intended level of the material by topic, not an official Learning Path name, a formal placement decision, or a promise that each grouping reproduces a local grade-level curriculum. For the current, named Learning Paths on the site, see What are Learning Paths?
How learners use Brilliant at different levels
| Learner stage | Common uses |
|---|---|
| Upper elementary | Build foundations in fractions, equations, geometry, and problem solving; provide enrichment for learners ready for additional challenge. |
| Middle and secondary school | Support current coursework, strengthen prerequisites, develop conceptual understanding, or explore more advanced mathematics. |
| College and adult learning | Refresh foundational skills, prepare for more advanced study, or explore topics not previously studied. |
Looking for a starting course rather than a coverage list? Use the course placement guide. For a description of what children typically learn in each school grade, see What math should my child know at each grade?.
Does Brilliant cover Algebra I?
Yes. Courses like Linear Equations, Coordinate Geometry, Linear Relationships, Exponents and Radicals, Visual Algebra, Introduction to Functions, Linear Systems, and Quadratics cover central Algebra I concepts, including linear equations and inequalities, graphs, functions, systems, exponents, radicals, and quadratics.
Brilliant does not package this material as one universal Algebra I syllabus because schools sequence topics differently. Compare the named courses with the learner’s syllabus when exact alignment matters.
Does Brilliant cover geometry?
Yes. Brilliant covers measurement, angles, area, circles, similarity, the Pythagorean theorem, surface area, volume, coordinate geometry, transformations, symmetry, and more advanced geometric reasoning across four courses.
Brilliant is especially useful for visual and interactive exploration. A school Geometry course may also require a specific sequence of constructions, formal proofs, vocabulary, and assessments, so check local requirements before using Brilliant as the only course resource.
Does Brilliant cover Algebra II and precalculus?
Yes. Courses like Quadratics, Exponentials and Logarithms, Trigonometric Functions, Polar Coordinate Plane, Complex Numbers, Polynomials, Equations and Curves, and Vectors and Matrices cover many topics found in Algebra II, Integrated Math II and III, and Precalculus. These include quadratics, exponential and logarithmic functions, trigonometric functions, polar coordinates, complex numbers, polynomials, advanced graphs, vectors, and matrices.
The material is distributed across focused courses rather than one course labeled “Algebra II” or “Precalculus.”
Does Brilliant cover calculus?
Yes. Brilliant’s Calculus course teaches key ideas in limits, derivatives, integrals, rates of change, accumulation, and infinite series through interactive problems and visual models.
For AP Calculus or another formal exam, pair Brilliant with the current official framework, calculator requirements, free-response practice, and full-length exams.
Does Brilliant teach probability and statistics?
Yes. Brilliant covers descriptive statistics, data visualization, probability, conditional probability, expected value, regression, probabilistic prediction, and Bayesian reasoning across the Everyday Math, Data Analysis, and Mind-Bending Math paths.
This range lets a learner begin with intuitive chance and data questions, then move into modeling, inference, and decision-making under uncertainty.
Does Brilliant cover elementary math?
Partly. The grade-banded math sequence begins with a fractions course labeled for grades 4–5, followed by equations for grades 5–6 and several grades 6–7 foundation courses. Brilliant also offers geometry, statistics, probability, and problem-solving material accessible to some elementary learners.
Brilliant does not present a complete K–3 arithmetic sequence. Parents seeking a full elementary curriculum should compare the catalog with the child’s school standards and use another source for uncovered topics and routine fluency practice.
Is Brilliant a complete math curriculum?
Brilliant has a broad, structured math curriculum from foundational through advanced topics. It can teach concepts, provide interactive practice, strengthen prerequisites, and extend learning beyond a standard syllabus.
“Complete,” however, depends on the requirement being measured. No single Brilliant path promises to reproduce every local course sequence, assignment type, proof requirement, state standard, or exam format.
| If the learner needs… | Use Brilliant for… | Also check… |
|---|---|---|
| Conceptual instruction and problem solving | Interactive lessons, models, feedback, and unfamiliar problems | Whether additional routine practice is needed |
| An exact school-course match | The closest courses and prerequisite topics | The teacher’s syllabus and required assessments |
| Common Core alignment | Lessons mapped to many grade 4 through high-school standards | The standard-by-standard mapping and any marked gaps |
| AP or other exam preparation | Understanding the underlying mathematics | The official framework, question formats, timing, and practice exams |
| School credit or formal placement | Evidence of completed work | The school’s own credit and placement policies |
Is Brilliant aligned with Common Core math standards?
Brilliant has a lesson-level mapping from Common Core grade 4 standards through high-school Algebra, Functions, Geometry, Number and Quantity, and Statistics and Probability. The map names the closest Brilliant lesson for each covered standard and explicitly marks standards with no direct lesson.
For the standards-level answer, use Common Core math coverage: grade-by-grade Brilliant lesson mapping. Keeping the detailed mapping on that page avoids duplicating hundreds of standards here.
