Free DSAT Diagnostic Test

Intro to the Math Section

Digital SAT Math Overview

  • Tests algebra, word problems, geometry, statistics and more; fewer types than the ACT.
  • The SAT repeats common question types — learning these boosts your score.
  • Built-in Desmos calculator helps with even hard problems.

How is it Structured?

Item Details
ModulesTwo modules (Module 1 and Module 2) with a 10‑minute break in between
Time35 minutes per module
Questions22 questions per module
AdaptivityModule 2 difficulty depends on Module 1 performance
OrderingWithin a module, questions go roughly from easiest to hardest
FormatsMultiple choice and Student‑Produced Response (typed answers)

How is it Scored?

  • Different questions have different weights (difficulty, skills tested, guessability).
  • No penalty for guessing.
  • Doing well on Module 1 matters — it unlocks the harder Module 2 needed for high scores.
  • Student‑Produced Responses have slightly bigger impact on your score.
  • Two experimental questions per module are unscored (you can’t tell which ones).
  • Scales aren’t tied to specific months; difficulty and scoring vary unpredictably.

What Does it Test?

Algebra (~35%)

  • Lines and linear inequalities
  • Systems of linear equations

Advanced Math (~35%)

  • Quadratics, exponential functions, absolute value
  • Polynomials, rationals, radicals, exponents

Problem Solving & Data Analysis (~15%)

  • Ratios, rates, proportions, percents
  • Scatterplots, probability, survey stats, margin of error

Geometry & Trigonometry (~15%)

  • Area, volume, angles, right triangles
  • Similar triangles, circles, trigonometry

How do I get started?

Well, we cover this in our getting started guide. But start by taking a diagnostic test so you can see the scope of the task ahead of you. If you take a Bluebook test, don’t review the specific questions yet, so that you can retake the test later. But do input your Bluebook results on our site so we can recommend practice topics based on what you got wrong!

For the math, you will need to master the built-in Desmos calculator if you want to maximize your score. We recommend this for both very weak and very strong math students.

After that, you just have to start learning topics. If you got a percent question wrong, review the topics of percents and then do enough practice on percents that you are sure you will never get another percent question wrong. Then, move on to your next mistake. Once you review all the topics from a given test, it’s time to take another practice test. We offer 1 free test on our site, and 7 more tests for subscribers. Subscribers also have access to hundreds of extended practice on many topics. We recommend taking the Resolve Prep tests first and then taking Bluebook tests when you get closer to your official test date.

Best of luck on your test prep journey!
