The SAT switched to a fully digital, adaptive format in March 2024. The Math section now looks like this:
| Module |
Questions |
Time |
Calculator |
| Module 1 (standard difficulty) |
22 questions |
35 minutes |
Permitted (Desmos built in) |
| Module 2 (adaptive: easier or harder) |
22 questions |
35 minutes |
Permitted (Desmos built in) |
| Total |
44 questions |
70 minutes |
|
Your performance on Module 1 determines whether you receive the harder or easier version of Module 2. To score 700+, you need to be routed into the harder module — which means performing well in Module 1 is especially important.
Key change from the paper SAT: The digital SAT has a built-in Desmos graphing calculator available on every question. You no longer need to memorise how to complete the square or manually solve systems — Desmos can do this for you if you know how to use it.
The Four Tested Domains
Every SAT Math question falls into one of four domains. Knowing the distribution helps you prioritise your study time:
| Domain |
Approx. % of Questions |
Key Skills |
| Algebra |
~35% |
Linear equations and systems, inequalities, linear functions |
| Advanced Math |
~35% |
Quadratics, polynomials, exponential functions, function notation |
| Problem Solving & Data Analysis |
~15% |
Ratios, rates, percentages, statistics, probability, two-way tables |
| Geometry & Trigonometry |
~15% |
Area, volume, Pythagorean theorem, circle equations, basic trig |
Algebra and Advanced Math together make up roughly 70% of the section. If your time is limited, these two domains give the highest return on study investment.
Algebra Tips ~35% of questions
What to expect
SAT Algebra questions test linear equations in one and two variables, systems of equations, linear inequalities, and linear functions. Many questions present a real-world scenario and ask you to set up and solve an equation — so reading comprehension matters even here.
Top strategies
- Plug in numbers when answer choices contain variables. Assign simple values (2, 3, 5) to the variables, compute the correct answer, then check which answer choice matches. This is often faster than solving algebraically.
- For systems of equations, pick the fastest method. Use substitution when one variable is already isolated (e.g. y = 2x + 3). Use elimination when the coefficients are easy to cancel. Use Desmos to graph both lines and read the intersection when neither method feels clean.
- Rewrite word problems as equations before computing. Write the equation in words first (“Total cost equals price per item times number of items plus shipping”), then translate to symbols. Students who jump straight to arithmetic often set up the wrong equation.
- Check your answer by substituting back. A 10-second check catches sign errors and arithmetic mistakes that are easy to make under time pressure.
Advanced Math Tips ~35% of questions
What to expect
Advanced Math covers quadratic equations and functions, polynomial operations, exponential growth and decay, function notation (including composition and inverse), and equivalent algebraic expressions. This is where many students lose points — these questions look intimidating but follow a small set of patterns.
Top strategies
- Know the three forms of a quadratic. Standard form (ax² + bx + c) is easiest to factor. Vertex form a(x − h)² + k tells you the vertex directly. Factored form a(x − r)(x − s) tells you the roots directly. The SAT frequently asks you to move between forms.
- Use Desmos for quadratics you can’t factor easily. Graph the equation and read the x-intercepts (roots), vertex, and y-intercept directly. This turns a 3-minute algebra problem into a 30-second graph-reading problem.
- For exponential questions, identify the base and the rate clearly. The formula y = a·bˣ: a is the initial value, b is the growth factor (b > 1 = growth, b < 1 = decay). Convert percentage rates to multipliers (a 4% annual increase → multiply by 1.04 each year).
- For function notation, substitute carefully and work outward. f(g(x)) means first apply g, then apply f to the result. Write out each substitution explicitly — mental shortcuts cause errors here.
Problem Solving & Data Analysis Tips ~15% of questions
What to expect
Data Analysis questions involve ratios, rates, unit conversions, percentages, proportional reasoning, basic statistics (mean, median, mode, range, standard deviation concepts), probability, and reading data from graphs, tables, and scatter plots. These questions require careful reading more than mathematical sophistication.
Top strategies
- Always check axis labels on graphs before computing. Many errors come from misreading the scale (e.g., the y-axis increments by 10, not 1) or ignoring units.
- Percent change formula: (new − old) / old × 100. Students who subtract without dividing will get the absolute change, not the percentage change. Read the question to confirm which one is asked.
- For two-way tables, always identify the correct denominator. “What percentage of women chose Option A?” divides by total women. “What percentage of Option A choosers are women?” divides by total Option A. These are different questions and different calculations.
- Distinguish mean from median in skewed distributions. If a data set has outliers (very high or very low values), the mean is pulled toward the outlier while the median is not. SAT questions often hinge on this distinction.
Geometry & Trigonometry Tips ~15% of questions
What to expect
Geometry questions cover angles (supplementary, vertical, interior angles of polygons), area and perimeter of triangles, circles (arc length, sector area, the equation of a circle), volume of solids, the Pythagorean theorem, similar triangles, and basic trigonometry (sin, cos, tan of right triangle angles, and the complementary angle relationship).
Top strategies
- Use the reference sheet — every time. The digital SAT provides a formula sheet at the start of the Math section with all area, volume, and special triangle formulas. Open it before any geometry problem. Students who memorise formulas incorrectly lose points they did not need to lose.
- Label everything on diagrams. Mark known side lengths, angles, and any special properties (right angle, parallel lines, equal segments) before you start computing. A labelled diagram makes the solution path visible.
- For the equation of a circle (x − h)² + (y − k)² = r², identify the centre and radius directly. The centre is (h, k) and the radius is √r². If the equation is not in standard form, complete the square to convert it.
- For trigonometry: SOH-CAH-TOA applies only in right triangles. sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite/adjacent. Know that sin(x) = cos(90° − x) — the SAT tests this complementary angle relationship frequently.
General Strategy: Pacing and Guessing
Pacing
You have 35 minutes for 22 questions — roughly 95 seconds per question. That sounds tight, but easy questions should take 30–45 seconds, leaving more time for harder ones. The practical rule:
- If you haven’t made progress on a question after 90 seconds, mark it and move on
- Return to marked questions with any time remaining
- Never spend more than 3 minutes on any single question in a first pass
Guessing
The digital SAT has no penalty for wrong answers. Never leave a question blank. If you are running out of time, pick an answer for every remaining question. Even a random guess has a 25% chance of being correct on four-choice questions — better than zero.
Strategic guessing: If you can eliminate even one answer choice, your odds improve to 33%. If you can eliminate two, you’re at 50%. Always eliminate before guessing.
Using Desmos strategically
The built-in Desmos calculator is one of the most underused advantages in the digital SAT. You can:
- Graph any equation and find intersection points, roots, and vertex without algebra
- Verify your algebraic solution by graphing both sides of an equation
- Solve quadratics visually by finding x-intercepts
- Use Desmos as a substitution checker — plug in the answer choices and see which one satisfies the equation
Practice using Desmos before test day. Students who haven’t used it before will waste time figuring out how to enter equations under pressure.
