Short answer. You can learn all of SAT Math free on video, in three steps: the 24 concepts the test expects you to know (one 45-minute lesson), then the hardest questions in each domain, then full Bluebook practice tests solved question by question after you take them yourself.
What it takes. About 13 hours of video across 14 lessons, all free on the Sigma Prep YouTube channel, watched more than 1.8 million times. This page puts them in the order to watch them.
Most SAT Math videos are either too long (a full "course" that re-teaches middle school) or too random (one trick, no plan). Here is every lesson on the channel in the order that actually builds a score, with what each one covers and when to watch it.
Every video solves real SAT-style problems at test speed, with no filler and no slides. Desmos shows up a lot, because on the digital SAT it is often the fastest route, not a backup.
Step 1: The 24 concepts the SAT expects you to know
The digital SAT gives you a reference sheet with basic geometry formulas. Everything else, you are expected to walk in knowing. This lesson covers all of it: 24 formulas and concepts, each drawn out and then used on a real SAT-style question.
If a topic is new to you, do not watch it all in one go. Watch one domain, then open the formula page for each topic in it: the formula, when the SAT uses it, and a practice question. The video chapters on YouTube jump to each topic.
- Algebra (starts at 0:39): slope-intercept form interpretation, parallel and perpendicular lines, no solution and infinite solutions, mixture problems.
- Advanced Math (starts at 7:41): exponent rules, exponential to radical, factoring and FOIL, quadratics, quadratic interpretations, discriminant, exponential equations, transformations.
- Problem-Solving and Data Analysis (starts at 18:39): unit conversions, percent change, statistics, standard deviation, probability, statistical inference.
- Geometry and Trigonometry (starts at 33:40): angle relationships, similar figures, proportionality, volume and surface area, trigonometry, circles.

Step 2: The hardest questions in each domain
Once the concepts are in place, the points you are still losing are on the hard questions in Module 2. These four lessons cover the question types that show up on nearly every test and eat the most time. Pause before each problem, try it, then watch the solution.
| Lesson | Length | What it covers |
|---|---|---|
| 12 hardest Algebra questions | 30 min | No solution and infinitely many solutions, systems, and the word problems that hide a linear equation. Solved with Desmos. |
| 20 hardest Advanced Math questions | 50 min | Quadratics, exponentials, and function questions, including Desmos regression. |
| 15 hardest Geometry and Trig questions | 59 min | Circles with tangent lines, similar figures, and the trig setups that quietly eat your clock. |
| 24 problems everyone gets wrong | 40 min | A mixed set from all four domains: the Module 2 questions that separate a 650 from a 750. |

Step 3: Full Bluebook practice tests, solved after you take them
This is where most of the learning happens. Take an official Bluebook practice test timed, score it, then watch only the questions you missed or guessed on. Each walkthrough is a perfect 800 with every question solved in order.
| Test | Length | Notes |
|---|---|---|
| Practice Test 4 | 42 min | The best first test to review. The walkthrough post also has the full review method. |
| Practice Test 5 | 44 min | Solved in about 35 of the 70 minutes, so you see where the time savings come from. |
| Practice Test 6 | 48 min | One of the harder Bluebook tests. |
| Practice Test 7 | 43 min | A speedrun: fast, every Desmos trick shown. |
| Practice Test 8 | 55 min | The longest test walkthrough, with extra time on the trickier problems. |
| Practice Test 9 | 47 min | All 44 questions in order. |
| Practice Test 10 | 48 min | Every shortcut and Desmos trick, with extra time on the hard ones. |
| Practice Test 11 | 47 min | The one students call the hardest math section. |
Never watch a walkthrough before taking the test. Once you have seen the questions solved, your score on that test stops meaning anything. If you are not sure which test to take next, see which SAT practice test is the most accurate.
Step 4: The 196 newest official questions
In August 2026, College Board added 196 new math questions to the official SAT Question Bank. All of them are solved in one long session, organized by domain, so you can skip to the one you are working on. Details and the domain-by-domain breakdown are in the August 2026 question bank post.

How to learn from a video instead of just watching it
Watching someone solve a problem feels like learning. Usually it is not, because you never had to come up with the first step yourself. Three rules fix that:
- Pause before every solution. Give yourself the time you would have on the test (about a minute and a half) and commit to a first step, even a wrong one.
- Write down the move, not the answer. For each problem you missed, write one line: what in the question should have told you what to do. That line is what transfers to test day.
- Re-test within a few days. Do a fresh problem of the same type. If you cannot do it cold, watch again. If you can, move on.
The full method for reviewing a practice test is in how to review SAT Math mistakes so they stop repeating.
When videos are not enough
Videos teach the method. The score comes from doing enough fresh problems that the method is automatic. That is the part a YouTube channel cannot give you, and it is what Sigma Prep is for: 7,300+ SAT Math questions and 24 full-length Math tests modeled on Bluebook, with a short video solution on every question that goes straight to the method. It covers SAT Math only, not Reading and Writing.
The first full-length test is free: take a timed SAT Math practice test.
