Whether you are reviewing for the first time or reinforcing what you already know, these resources are built to help you improve your score efficiently.
Quick Answer: Your Central Directory for SAT Prep
This page is a directory of free guides for Digital SAT Grammar and Math. The goal is simple: find your weak areas and fix them fast. Start with a full-length practice test to get a baseline score. Then use the links below to study only the topics you need to improve. Do not waste time on skills you already know.
Many students waste weeks reviewing material they have already mastered. A targeted approach saves time and raises scores faster. The Digital SAT tests a specific set of grammar rules and math concepts. Once you know which ones give you trouble, you can fix them with focused practice. This grammar and math hub organizes those resources so you can move from diagnosis to improvement in one session.
Official College Board guidance recommends starting with a full-length practice test in Bluebook to establish your baseline. From there, you identify your weakest domains and drill those specific skills. This hub follows that same logic. Each link below leads to a complete guide with rules, examples, and practice strategies.
How to Use This Resource Hub
Follow these four steps to get the most from the grammar and math hub.
- Diagnose: Take a full-length Digital SAT practice test in Bluebook. This gives you a baseline score and reveals your weak topics. Record your score for each domain.
- Focus: Use the directories below to pick a specific skill you need to improve. For example, verb tenses or systems of equations. Do not pick more than two topics at a time.
- Practice: Read the guide for that topic. Then complete 10 to 15 targeted practice questions. Review every mistake and write down the rule you missed.
- Track: Retake a practice section to see if your score improves. Repeat the cycle for each weak area. Move on only when you hit 90 percent accuracy on that topic.
This cycle works because it mirrors the way high-scoring students prepare. They do not study everything. They study their specific gaps. The resources below are organized by the exact domains tested on the Digital SAT, so you can match your practice to the test structure.

Verb Tense and Agreement
Verb tense questions appear in nearly every Reading and Writing module. The Digital SAT tests your ability to match verb tense to the time frame established by the sentence. The most common mistake students make is choosing a verb form that sounds right but does not match the time clue in the sentence. Look for signal words like "yesterday," "each year," or "by the time" to determine the correct tense. Subject-verb agreement is simpler: singular subjects take singular verbs, and plural subjects take plural verbs. The trap is when a phrase comes between the subject and the verb, making the subject hard to spot.
Sentence Structure and Modifiers
Modifier errors are one of the most tested grammar concepts on the Digital SAT. A dangling modifier occurs when the subject of the modifier does not match the subject of the main clause. For example, "Walking to the store, the rain started" is wrong because the rain cannot walk. The fix is to put the correct subject right after the comma. The Digital SAT also tests your ability to spot misplaced modifiers that are too far from the word they describe. These questions reward careful reading more than grammar knowledge.
Reading and Writing Domains
The Digital SAT Reading and Writing section is divided into four domains: Craft and Structure, Information and Ideas, Standard English Conventions, and Expression of Ideas. Each domain tests a different skill set. Standard English Conventions covers grammar rules like punctuation, verb tense, and sentence boundaries. Expression of Ideas tests your ability to make writing clearer and more effective. Knowing which domain a question belongs to helps you apply the right strategy. For example, a punctuation question from Standard English Conventions requires a different approach than a transition word question from Expression of Ideas.

Systems of Equations
Systems of equations appear in both modules of the Digital SAT Math section. The fastest way to solve them is with Desmos, the built-in graphing calculator in Bluebook. Enter both equations as they are written, and Desmos shows you the intersection point. This method works for linear systems, quadratic systems, and systems with exponential functions. The most common mistake students make is forgetting to check whether the system has one solution, no solution, or infinitely many solutions. Parallel lines mean no solution. Identical lines mean infinitely many solutions. Desmos shows you this instantly if you know what to look for.
Graphing and Intercepts
Finding the y-intercept of a function is a common Digital SAT question. In Desmos, you type the equation and look for where the graph crosses the y-axis. The y-intercept always has an x-coordinate of zero. You can also use Desmos to create a table and see the value when x equals zero. This method works for linear equations, quadratics, and higher-order polynomials. The trap is that some questions ask for the x-intercept instead. Read the question carefully. If the question asks for the y-intercept, the answer is the point where x equals zero. If it asks for the x-intercept, the answer is where y equals zero.
Common Mistakes That Lower Your Score
Knowing the rules is only half the battle. The other half is avoiding the traps built into every Digital SAT question. Here are three patterns that cause students to lose points on Grammar and Math fundamentals.
Trap 1: Choosing the answer that sounds right
In grammar questions, the answer that sounds natural in conversation is often wrong. The Digital SAT tests formal written English, not spoken English. For example, "Me and my friend went to the store" sounds natural in conversation but is incorrect on the test. The correct version is "My friend and I went to the store." Train yourself to check the grammar rule before trusting your ear.
Trap 2: Solving math problems without Desmos
Many students solve math problems by hand because they think it is faster or because they do not trust the calculator. On the Digital SAT, Desmos is your primary tool. Use it for every question that allows it. The students who score highest use Desmos to check their work even when they solve by hand. This catches arithmetic errors and saves time.
Trap 3: Rushing through the first module
The Digital SAT uses adaptive testing. Your performance on the first module determines the difficulty of the second module. If you rush through the first module and make careless mistakes, you get an easier second module. An easier module caps your maximum score. Take your time on the first module. Double-check every answer before moving on.
Common Questions
What should I do first?
Start with a diagnostic test in Bluebook. Do not study anything until you have a baseline score. The diagnostic tells you which domains need work and which ones you can skip. This saves hours of unnecessary study time.
How many practice questions should I do per topic?
Aim for 10 to 15 targeted questions per topic. If you score below 70 percent, review the rules and try another set of 10. If you score above 90 percent, move to the next topic. Do not do 50 questions on a topic you already know.
Should I use Khan Academy for SAT practice?
Yes. Khan Academy offers free, official SAT practice aligned with the Digital SAT. Their questions are written by College Board and match the style of the actual test. Use their skill-based practice to drill specific topics after you identify your weak areas from a diagnostic test.
How do I know if I need a tutor?
Get a tutor if your practice scores stay flat for three weeks despite consistent practice. Also get help if you struggle with timing on every section or if you cannot identify why you are missing questions. A tutor helps you see patterns in your mistakes that you might miss on your own.
What is the best way to track my progress?
Use the official Digital SAT score calculator to convert your raw score to a scaled score after each practice test. Track your score for each domain separately. If your overall score goes up but your grammar score stays the same, you know exactly where to focus next.
Next Steps for Score Improvement
Once you finish the resources above, use this checklist to decide your next move.
When to move on to harder topics
If you score above 90 percent accuracy on practice questions for a topic, shift to a new weak area. Do not waste time on skills you already know. The Digital SAT covers a wide range of content, and your time is limited. Focus on the topics that give you the most trouble first.
When to get tutoring support
Get a tutor if your practice scores stay flat for three weeks, if you struggle with timing on every section, or if you need a structured plan to stay on track. A good tutor helps you identify the specific skill gaps that are holding your score back. They also provide accountability, which matters when you are studying on your own.
How to track your raw score
Use the official Digital SAT score calculator to convert your raw score (number correct) to a scaled score. This helps you set a target for test day. For example, if you want a 1400, you need roughly 52 out of 54 correct in Math and 52 out of 54 in Reading and Writing. Knowing these numbers helps you set realistic goals for each practice session.
How The Test Advantage Can Help

Frequently Asked Questions
What grammar fundamentals must I know for the Digital SAT?
Seven grammar rules cover 80% of Digital SAT grammar questions: (1) subject-verb agreement (including with intervening phrases and collective nouns), (2) pronoun-antecedent agreement (number and gender), (3) comma usage (after introductory elements, around non-restrictive clauses, in compound sentences with FANBOYS), (4) semicolons (between independent clauses), (5) colons (introducing a list or explanation after an independent clause), (6) apostrophes (possessives versus contractions), and (7) modifier placement (participial phrases and dangling modifiers).
What math fundamentals should I prioritize first for the Digital SAT?
Prioritize in this order: (1) linear equations and inequalities (appearing in 25 to 30% of math questions), (2) systems of two equations (5 to 8% of questions), (3) quadratic equations and functions (10 to 15%), (4) percentages and ratios (8 to 12%), (5) coordinate geometry — slope, intercepts, distance (8 to 10%). These five areas together account for roughly 65 to 75% of all math questions. Trigonometry and complex numbers appear rarely and should be studied last.
Can I improve my Digital SAT score by only studying grammar and math fundamentals?
For students scoring below 1350, yes — grammar and math fundamentals are the primary gap. Most errors below 1350 are on question types that test basic rules rather than hard-concept questions. For students scoring 1350 to 1450, fundamentals are already mostly mastered, and improvement comes from harder question types and strategy refinement. Above 1450, specific hard-concept questions (advanced algebra, complex vocabulary, hard reasoning) determine score — fundamentals alone are insufficient at that level.
