The digital SAT provides a formula reference sheet at the start of the Math section. It's accessible through the testing interface throughout both Math modules. Knowing exactly what's on it — and what isn't — is one of the most practical things you can do before your test date.
Here's the thing: most students don't use the formula sheet efficiently. They either forget it exists or they spend time scrolling through it during the test when they could have memorized those formulas in advance. The formula sheet is a backup, not a crutch. The students who score highest are the ones who know the formulas cold and use the sheet only to double-check.
The SAT math reference sheet includes the following:
Area formulas:
Volume formulas:
Pythagorean theorem and special right triangles:
Additional facts provided:
That's the complete list. Twelve formulas/facts. Print them out and look at them — it's a short list, and many test-takers are surprised by how basic some of it is.
Here's where most students make a costly mistake: they assume that if a formula isn't on the sheet, it won't be tested. That's wrong. The SAT tests plenty of concepts and formulas that aren't provided. You're expected to know these from your math education.
Algebra formulas you must know:
Geometry concepts not on the sheet:
Statistics and data analysis:
Trigonometry basics:
None of these are on the formula sheet. All of them appear in the actual SAT Math section regularly.
On test day, the formula sheet is available from the start of the Math section — you don't have to do anything special to access it. In the Bluebook testing interface, there's a reference button that pulls it up in a sidebar without leaving the question.
Here's the strategic approach: don't rely on it during timed practice. When you practice, work through geometry and formula-based problems without looking at the sheet. If you get a problem wrong because you couldn't remember a volume formula, that's actually valuable — you identified a gap. Then review the formula and practice that problem type again. By test day, the formulas on the sheet should feel redundant — things you already know.
If you hit a problem on the real test where you genuinely can't remember a formula that is on the sheet, take two seconds to pull it up. It's better to use it than to guess at a formula you're uncertain about. But those situations should be rare if you've prepared properly.
Statistically, the volume formulas — especially cylinder and sphere — show up in Digital SAT problems more than the rectangle area or basic triangle formulas (which most students know automatically). If you're going to get extra reps on any part of the sheet, make it the 3D shapes.
Typical SAT geometry problems involving these formulas don't just ask you to plug in numbers. They ask compound questions: "A cylinder is melted down and reformed into a sphere of the same volume — what's the radius of the sphere?" You need to set the cylinder volume formula equal to the sphere volume formula and solve for the unknown. Just knowing the formula isn't enough; you need to know how to use it in multi-step problems.
The khan academy dsat practice sections include geometry problems that require multi-step formula application. Work through those problem sets specifically to build fluency with the provided formulas in realistic contexts.
These special right triangles appear in the reference sheet and show up regularly on the SAT. Know them cold — including when to apply each one and how to derive missing side lengths from the ratios.
For the 30-60-90 triangle with hypotenuse 2x: the short leg is x and the long leg is x√3. For the 45-45-90 triangle with legs of length x: the hypotenuse is x√2.
SAT problems involving these triangles often embed them inside larger figures — an equilateral triangle divided into two 30-60-90 triangles, or a square divided diagonally into two 45-45-90 triangles. Recognizing when you're looking at one of these special triangles, even when it's not obvious, is the actual skill being tested.

What is one of the most effective ways to reduce anxiety about the Digital SAT?
Answer: B. Familiarizing yourself with the test format and tools beforehand.
One of the most effective ways to reduce test anxiety is to thoroughly understand what to expect on test day. By familiarizing yourself with the Digital SAT's adaptive format, question types, and built-in digital tools like Desmos, you can approach the exam with greater confidence. This preparation eliminates surprises and allows you to focus on the content rather than the mechanics of the test.
On the Digital SAT, what should you do with the 'Mark for Review' flag during a module?
Answer: B. Flag uncertain answers so you can revisit them if time remains
The Mark for Review flag is a tool to track questions you are unsure about, allowing efficient use of remaining time within the same module.
A ratio problem states that for every 3 apples there are 5 oranges. If there are 24 apples, what strategy finds the number of oranges fastest?
Answer: A. Set up a proportion: 3/5 = 24/x
Setting up the proportion 3/5 = 24/x and cross-multiplying gives x = 40 oranges directly.
What does the countdown timer in Bluebook display during the Digital SAT?
Answer: B. Time remaining for the current module only
The Bluebook timer shows the time remaining for the active module, helping students pace themselves within that section.
If you're two or three weeks out from your test date, formula review should be a small but consistent part of your daily routine. Five minutes in the morning — write out the formula sheet from memory, check it, identify any gaps. Do that for two weeks and you'll have the sheet memorized completely without it feeling like a grind.
Spend more time on the formulas that aren't provided — the quadratic formula especially, since it's testable and not intuitive to derive under pressure. Know when to factor versus when to use the quadratic formula (factoring is faster when it works; the formula is the backup). Know the vertex formula h = -b/(2a) for finding the vertex of a parabola without completing the square.
The Digital SAT Math section is 44 questions across two adaptive modules. Formula fluency — both the provided formulas and the ones you've memorized — removes a category of potential errors from your exam. That's points you're not leaving on the table because you couldn't remember a volume formula or blanked on the distance formula.
For more practice on the types of math problems where these formulas are applied, work through the dsat practice test questions in the geometry and advanced math categories. You want to see these formulas in context — embedded in multi-step problems — not just isolated in a list.
