14 Best Brilliant Courses in 2026 (Honest Guide + What to Take First)

Last updated: October 2026. Written by Josh Hutcheson, OnlineCourseing editor. Every course below was re-opened on Brilliant on 22 October 2026, and prices were read from Brilliant’s own subscribe page that day. Brilliant does not pay us: we have no affiliate relationship with it. See our review methodology.

Our verdict

One naming note before the list. Brilliant is renaming its catalog: what it used to call courses are now “topics”, levels are “units” and lessons are “concepts”. The course pages we link still show course names with lesson and exercise counts, so that is the language we use here. Your progress carries over.

What Brilliant actually is (and isn’t)

Every Brilliant course is a sequence of interactive steps: you drag a diagram, predict an outcome or solve a small puzzle, and the explanation adapts to your answer. Premium now also includes Koji, Brilliant’s built-in AI tutor, which sits inside a lesson and helps when you are stuck. The format rewards consistency: one concept a day adds up in a way that a 10-hour video course often does not, because there is nothing to fall behind on.

What it is not: a route to a credential, a place to write real code in a real editor, or a reference you can look things up in. Brilliant’s own help center describes it as a supplement to formal education and a skill-building tool, and that is the right frame. Think of it as a gym for quantitative thinking.

Best Brilliant courses for programming & computer science

1. Thinking in Code

Thinking in Code (48 lessons, 618 exercises) teaches the mental models behind programming (sequencing, loops, conditions, state) before syntax gets in the way. If a blank code editor has beaten you before, this is the gentlest serious start we know of, and it is the course Brilliant lists first on the Programming & CS list on its subscribe page.

2. Computer Science Fundamentals

Computer Science Fundamentals (39 lessons, 229 exercises) covers arrays, sorting, searching and the efficiency ideas every developer meets eventually, taught visually. Take it before a data-structures course elsewhere and the later material stops feeling abstract.

3. The Python series (Thinking in Python to Object-Oriented Programming)

Brilliant’s Python track now runs six courses: Thinking in Python (70 lessons, 943 exercises), Functions in Python (41 lessons), Recursion in Python (11 lessons), Algorithms in Python, Data Structures in Python (26 lessons, 345 exercises) and Object-Oriented Programming in Python (14 lessons). It is puzzle-based rather than project-based, so it is excellent for understanding why code behaves the way it does. Pair it with a project course once you can read Python comfortably; our best coding websites guide covers where to build real things.

4. Algorithmic Thinking

Algorithmic Thinking (22 lessons, 249 exercises) shows how computer scientists break a problem down: greedy choices, dynamic programming, and how to tell whether an approach will scale. We would give this to a strong teenager, or to a product manager who wants to reason about what engineers are building.

Best Brilliant courses for AI & data

5. How AI Works

How AI Works (31 lessons, 94 exercises) looks under the hood of generative AI and large language models: tokens, training, prediction, and why a model can sound confident and still be wrong. It is the course we would hand to a marketer, a manager or a parent who wants a mechanical understanding of the tools everyone is talking about, without any code.

6. Introduction to Neural Networks

Introduction to Neural Networks (15 lessons, 112 exercises) is the follow-on: you build intuition for weights, activation functions and how a network learns by playing with very small networks. It will not make you a machine learning engineer, but every ML course you take afterward will make more sense.

7. The data analysis track (Exploring Data Visually to Regression)

Five courses form a solid conceptual spine for data work: Exploring Data Visually (29 lessons), Probability in Data (19 lessons), Clustering & Classification (27 lessons), Regression (23 lessons) and Predicting with Probability (15 lessons). The honest caveat: you never touch a real messy dataset or a real tool here. When you are ready for pandas, SQL and spreadsheets full of missing values, that is DataCamp’s lane.

8. Solving Equations, then Linear Equations

Brilliant retired its old Visual Algebra course; algebra now runs through its Algebra Fundamentals path. Start with Solving Equations (68 lessons, 1,159 exercises), which introduces variables from scratch, then move to Linear Equations (68 lessons, 1,201 exercises) and the shorter Real-World Algebra (12 lessons) for formulas in practical settings. If algebra was ever a wall of symbols for you, this is the best confidence repair on the platform.

9. Everyday Statistics + Probability and Chance

Everyday Statistics (36 lessons, 434 exercises) and Probability and Chance (31 lessons, 406 exercises) are the statistical-literacy pair: averages and spread, base rates, and why a headline about risk can mislead. For most adults this is the highest real-life return on the platform; you will use it at the doctor’s office and every time a poll is in the news. Bayesian Probability (13 lessons) is the natural next step.

10. Calculus

Calculus (42 lessons, 353 exercises) builds the ideas (rates of change, accumulation, limits) that lecture courses often rush past. Students taking calculus at school can pair it with Limits and Derivatives (37 lessons, 598 exercises) for far more practice than the overview course alone gives.

Best Brilliant courses for science & logic

11. Scientific Thinking

Scientific Thinking (40 lessons, 557 exercises) teaches you to reason like a physicist with levers, orbits, springs and circuits, without an equation dump. It is the course that makes many people fall for the format. Science Puzzles (one puzzle a day for a month) is the companion habit.

12. Quantum Computing

Quantum Computing (26 lessons, 157 exercises), built with Microsoft and Alphabet X, is a rigorous but gentle introduction to qubits and quantum gates. It is one of the few places a curious person can build real intuition here without graduate-level math.

13. Circuits

Circuits (31 lessons, 394 exercises) covers the physics of electricity: current, voltage, resistance and how real circuits behave. It replaces the Kurzgesagt collaboration on our list, which is no longer in Brilliant’s catalog. Pair it with Digital Circuits if you want the bridge to how computers work at the hardware level.

14. Logic (+ 100 Days of Puzzles)

Logic (26 lessons, 351 exercises) is where most people should honestly start: codebreaking, ordering puzzles and logical robots that sharpen how you argue and read claims. 100 Days of Puzzles (one puzzle a day across logic, algebra, geometry and probability) is the habit-forming companion.

What order should you take Brilliant courses in?

On the free plan you must work through a topic in order; Premium lets you jump to any concept. That matters more than it sounds: if you already know the basics of a subject, the free plan makes you click through them first.

Does Brilliant give certificates?

No. Brilliant’s help center says plainly that it does not offer completion certificates, course credits, academic degrees or professional certifications. What you get instead is a profile showing completed courses, streaks and experience points. Brilliant is accredited by the Accrediting Commission for Schools, Western Association of Schools and Colleges (ACS WASC), which is an independent check on its curriculum, but that accreditation does not turn into college credit or anything you can list as a credential.

If a shareable certificate matters, the equivalent lanes are Coursera for university and company-backed certificates in math, data and computer science, and DataCamp for data-career tracks. Both pair well with Brilliant rather than replacing it.

Brilliant pricing (and the free tier)

When we checked brilliant.org/subscribe on 22 October 2026, Individual Premium was listed at $30 a month, and the six-seat Family plan at $40 a month on annual billing or $60 a month on monthly billing. Brilliant labels the annual option “save 33%”, and its help center says prices vary by plan and subscription length, so confirm the figure at checkout. There is also a Single Child plan, with one Premium seat for a child whose account a parent manages.

Discounts are rare. Brilliant’s help center says it runs one sale a year, at Black Friday and Cyber Monday, and otherwise only through occasional partnerships, so a mid-year “coupon” you see advertised is usually a sponsor link from a YouTube creator. Free trials appear sometimes, depend on your account and platform, and require a card; Brilliant advises canceling at least 24 hours before the trial ends. That last detail is behind most of the angry one-star reviews: people forget to cancel and are charged for a year.

K-12 teachers and their students may qualify for free classroom access through Brilliant for Educators. Classroom access covers the full catalog but not Koji.

Who should choose something else?

Skip Brilliant if you need job-ready skills on a deadline (a Coursera Professional Certificate or a project course gets you further, faster), if you learn best from a person explaining things out loud (Brilliant is text, diagrams and the Koji chat), or if you want to write real code in real tools from day one. Choose it if you want durable intuition in math and computing and a daily learning habit that actually sticks.

Reddit’s math communities add one more group: people learning a subject for the first time with no other resource. A recurring complaint is that some courses jump ahead quickly and give too few practice problems to lock a skill in. Brilliant works best alongside a textbook or a class, or for reviewing something you half-know.

Brilliant vs the alternatives, honestly

The honest free comparison is Khan Academy, which covers much of the same school math at $0 in a more traditional video-and-exercise format. Brilliant earns its subscription when the interactive format keeps you showing up daily where videos did not. That behavioral difference, more than the course list, is what you are paying for. For a wider shortlist, see our ranking of the best online learning platforms and our DataCamp alternatives comparison.

Is Brilliant good for kids and teens?

Yes, and it now reaches younger kids than it used to. Brilliant’s math topics are labeled by grade: Math Foundations for grades 4–7, Algebra Fundamentals for grades 7–9, Intermediate Algebra for grades 8–11 and Advanced Algebra for grades 11–12. It also runs a K–5 math practice beta, and it is a member of the kidSAFE Seal Program. For a mathy teenager the puzzle format reads as a game rather than homework. The Single Child plan lets a parent manage one child’s account and see their progress.

For young children who want to code, block-based tools are still the better on-ramp; our Scratch courses guide covers that age group. One practical tip from parents: do the first week alongside your child. The streak mechanic works much better with a rival in the house.

Is Brilliant worth it? What learners say

Brilliant holds a 4.2 TrustScore on Trustpilot (22 October 2026). We read the 45 newest reviews: most are five stars, and most of those praise fast, friendly support. The one-star reviews follow one pattern: a free trial or an annual plan renewed, the reviewer forgot to cancel, and a refund was harder to get than expected. Several five-star reviews describe the opposite experience, a refund granted within hours. Read the renewal date when you subscribe and set a reminder.

Reddit is more divided than Trustpilot. In r/learnmath and r/math threads, the most-upvoted criticism is that Brilliant is better for review and mental exercise than for learning a subject from zero, because it can take big leaps without enough practice. The defenders are often heavy users with thousands of problems solved, who describe it as a supplement to a book or a class and enjoy the puzzle courses most. Several people recommend the same approach we do: use the free plan for a week or two and decide based on whether you keep coming back.

Our take

How to get the most out of the free plan

The free plan gives you two keys a day, and each key opens one concept or practice set. That is enough to test the format properly if you are deliberate about it:

• Pick one course and stay with it for a week. Logic or Thinking in Code are good tests, because they show the format at its best.
• Spend your two keys at the same time every day. Brilliant is built around streaks, and the habit is what you are evaluating.
• Notice where you get stuck. On the free plan the Koji tutor is a short preview. If you keep wanting it, that is the strongest argument for Premium.
• Decide before any trial converts. If you start a Premium trial, note the end date; Brilliant asks you to cancel at least 24 hours before it ends.

If you are on the fence near the end of the year, wait: the one annual sale runs at Black Friday and Cyber Monday.

Brilliant for test prep (SAT, ACT, GRE and GMAT)

Brilliant publishes coverage maps in its help center showing how its math topics line up with the digital SAT, PSAT, ACT, GED, GRE quant and GMAT quant sections, plus school standards such as Common Core and AP Precalculus. That is useful for building the underlying skills months before a test. It is not a substitute for timed practice tests and question banks from a dedicated prep course, because Brilliant does not simulate the exam itself.

FAQs

What are the best Brilliant courses to start with?

Start with Logic or Thinking in Code. Logic is the best introduction to Brilliant’s puzzle-first style, and Thinking in Code is the best start if programming is your goal. How AI Works is the standout for professionals who want to understand generative AI and large language models.

Does Brilliant give certificates when you finish a course?

No. Brilliant’s help center says it does not offer completion certificates, course credit, degrees or professional certifications. It is accredited by ACS WASC, but that does not convert into credit. Pair it with Coursera or DataCamp if you need a shareable certificate.

How much does Brilliant cost?

On 22 October 2026 Brilliant’s subscribe page listed Individual Premium at $30 a month and the six-seat Family plan at $40 a month on annual billing or $60 a month on monthly billing. Brilliant says prices vary by plan, so check the price at checkout.

Is Brilliant free?

Partly. Brilliant Free gives you two keys a day, each opening one concept or practice set, with occasional ads and a short preview of the Koji tutor. You must work through topics in order. Premium removes the limits.

Is Brilliant good for learning to code?

It is excellent for learning to think like a programmer: logic, algorithms and how Python code behaves. It is not enough on its own, because you never build a real project in a real development environment. Pair it with a project-based platform.

Does Brilliant ever go on sale?

Rarely. Brilliant’s help center says it runs one sale a year, at Black Friday and Cyber Monday, and otherwise offers discounts only through occasional partnerships.

Is Brilliant Premium worth it?

If the format clicks during a week on the free plan and you will use it 10 to 15 minutes most days, yes. If you need certificates or job-ready projects, spend the money on a platform that provides them.
