Yes, for the mathematics — and the answer differs by exam. Brilliant teaches most of the content assessed on the Regents Algebra I and Algebra II exams, and a narrower slice of the Geometry exam. What it does not teach is the exam itself: the question formats, the timing, and the rubrics that score the constructed-response parts. Use Brilliant to understand the math, and past Regents papers with their scoring keys for everything exam-specific.
The three exams — Algebra I, Geometry, and Algebra II — are sat at the end of the matching course, each counts toward a New York diploma, and each tests different content. So the useful question is not whether Brilliant covers “the Regents,” but whether it covers the one you are taking. Here it is exam by exam.
Regents Algebra I: what Brilliant teaches
This is Brilliant’s strongest match of the three: linear equations and inequalities, systems, quadratics in every solving method, function notation, exponential growth and decay, and the data strand all have dedicated courses.
| Brilliant course | What it gets you for Algebra I | Start here |
|---|---|---|
| Linear Expressions & Equations (59 lessons) | Multi-step solving, negative and fractional coefficients, one solution against none or infinitely many | Combining Terms |
| Linear Functions (45 lessons) | Slope, intercepts in context, all three forms of a line, linear inequalities | Proportional Relationships |
| Linear Systems (24 lessons) | Solving by graphing and elimination, writing a system from word constraints, inequality systems | Graphing Systems of Equations |
| Quadratics (69 lessons) | Factoring, completing the square, the quadratic formula, the discriminant, vertex form, axis of symmetry | Undistributing |
| Introduction to Functions (68 lessons) | Function rules and notation, domain and range, the vertical line test, shifts | Writing Rules |
| Exponential Functions (63 lessons) | Growth and decay, finding the base and starting value, exponential against linear growth | Growing |
For the data questions, Everyday Statistics covers box plots, center, and spread — open Comparing Distributions — and Regression covers scatter plots and lines of fit, starting at Calculating Error.
Short on time? Do Quadratics and Linear Functions and skip the rest — between them they carry more of this exam than anything else on the list.
Get from class materials: justifying each step of a solve in writing, naming the parts of a polynomial in standard form, classifying sums and products as rational or irrational, solving a line-and-parabola system, finding solutions where two graphs intersect, and correlation against causation.
Regents Geometry: what Brilliant teaches
For this exam Brilliant is a coordinate-and-transformations resource, not a synthetic geometry course: strong on transformations, the coordinate plane, and right-triangle trigonometry, and silent on the proof-writing that carries a large share of the paper.
| Brilliant course | What it gets you for Geometry | Start here |
|---|---|---|
| Geometry and Measurement (25 lessons) | Angles made by intersecting and parallel lines, polygon angle sums, scale factor, volume | Angles Made by Lines |
| Coordinate Transformations (60 lessons) | Reflections, rotations, translations, and dilations by coordinates; symmetry; similar figures | Reflecting Coordinates |
| Coordinate Geometry (44 lessons) | Distance from coordinates, the Pythagorean theorem, the equation of a circle, area on a grid | Pythagoras’ Theorem |
| Trigonometric Functions (62 lessons) | The 30-60-90 and 45-45-90 triangles; sine and cosine of complementary angles | Triangles and the Unit Circle |
Parallel and perpendicular slopes sit in Linear Functions rather than a geometry course, at Perpendicular Lines.
Short on time? Coordinate Transformations first — Dilating Points through Identifying Similarity is a fast run.
Get from class materials: everything about circles — inscribed and central angles, arcs, chords, tangents, arc length and sector area; the congruence and similarity criteria and the proofs built on them; parallelogram theorems; compass-and-straightedge constructions; coordinate proofs; partitioning a segment in a ratio; cross sections and solids of rotation; and the modeling questions about density and design. That is a substantial share of this exam.
Regents Algebra II: what Brilliant teaches
Strong again, and in places deeper than the exam requires: rational exponents, complex numbers, polynomial factoring and root behavior, logarithms, and the full radian-and-unit-circle treatment of trigonometry are all here.
| Brilliant course | What it gets you for Algebra II | Start here |
|---|---|---|
| Exponents & Radicals (83 lessons) | Rational exponents, converting between radical and exponent form, simplifying radicals | Exponent One Half |
| Complex Plane (50 lessons) | The imaginary unit, adding and multiplying complex numbers, multiplication on the plane | Combining Complex Numbers |
| Polynomials (52 lessons) | Polynomial arithmetic, factoring past the quadratic case, roots and factored form, sign regions | Root Finding |
| Exponential Functions (63 lessons) | Logarithms and their identities, log and exponential form, solving equations with logs | Log-Exponent Pairs |
| Trigonometric Functions (62 lessons) | Radian measure, unit circle values, amplitude, midline and period, solving trig equations | Radians |
| Equations & Curves (61 lessons) | Simplifying rational expressions, general roots, multi-step graph transformations | Simplify Rational Expressions |
For the probability questions, Probability and Chance and Probability in Data cover sample spaces, Venn diagrams, the addition rule, and Conditional Probability. Inverse functions live in Inverting a Function.
Short on time? Trigonometric Functions and Exponential Functions. Radians, the unit circle, and logarithms are new to most students in this course and are heavily assessed.
Get from class materials: sequences and series — recursive and explicit rules, sigma notation, the arithmetic and geometric series formulas — plus the remainder theorem, polynomial long division, building a model from a multi-step context, solving rational and radical equations and checking for extraneous roots, average rate of change, and statistical inference from samples and simulations.
What Brilliant will not do for you
Brilliant has no Regents-format practice: no full-length timed papers, no sections built to NYSED’s specifications, and nothing that teaches you how the constructed-response questions are scored. Those are graded against published rubrics, and points go missing on work that is mathematically right but presented in a way the rubric does not credit.
The New York State Education Department publishes every past Regents exam with its scoring key and model responses. Working recent papers under timed conditions is the highest-value Regents-specific practice available, and reading the model responses beside your own work is the only way to learn what a full-credit answer looks like. Use them alongside Brilliant: when a paper exposes a topic you cannot do, come back for the lesson that teaches it.
How this mapping was made
Brilliant’s curriculum team maps each math skill to the standard it fits most closely, using the New York State Next Generation Mathematics Learning Standards as scoped by NYSED’s Educator Guide blueprint for each Regents exam, and the data behind this page was pulled on August 27, 2026 against the live course catalog. The full standard-by-standard map is at New York Regents math coverage.
Frequently asked questions
I’m retaking a Regents exam. Where should I start?
With the paper, not with a course. Score a recent past paper against its key, group the misses by topic, and open only the Brilliant lessons that match. Retakes usually turn on two or three topics rather than the whole syllabus.
Does Brilliant teach the two-column proofs on the Geometry exam?
No. It teaches the relationships a proof uses — congruence through transformations, similarity, angle relationships, coordinate distance — but not the formal writing of a proof or the criteria it cites. Get proof practice from your class and from past papers, whose model responses show what earns full credit.
My Algebra I class has gotten away from me. What comes before these courses?
Usually multi-step equation solving, signed numbers, or reading the coordinate plane. Solving Equations and Coordinate Plane are the repair points; fix the gap there, then rejoin the Algebra I path above. If it is wide, tell your teacher.
