Mastering the SAT: Part 2 (SAT Writing)
Master SAT Writing with crisp grammar, punctuation, and rhetoric strategies. Learn to predict answers, prefer concise choices, and review mistakes with official practice. Read on to explore these insights and more in Part 2 of our series on everything you need to score well on the SAT.
I. Introduction to SAT Writing
Within each Reading & Writing module, just under half of the questions (46%) are writing-focused, meaning that these questions test skills involving how most effectively to convey information using standard written English. By contrast, the reading-focused questions discussed in Part 1 of this series test the ability to interpret and critically engage with written texts. Though there are slightly fewer writing-focused questions than reading-focused ones, writing-focused questions ultimately contribute to just under one quarter of a student’s composite SAT score.
Although each passage is short, with only one question associated with it, students face a handful of challenges that arise from this format: there are several different question types to keep track of, the answer choices can be tricky to navigate, and the variety of passages, questions, and answer choices can be exhausting to work through, especially given the added pressure of a ticking clock.
This article – the second in a three-part series – elaborates on these challenges and offers effective techniques and strategies students can employ to master SAT writing-focused questions.
II. Understanding the SAT Writing Section
Structure & Format
When you sit for your official SAT, the Reading & Writing section will come first. The section involves two modules, each 32 minutes long and containing 27 questions. There is no break between the modules, meaning this section is long—64 minutes altogether. In total, there are eleven Reading & Writing question types, four of which are writing-focused. And within each module, the questions always follow the same order.
Types of Questions
The College Board divides the writing-focused questions into two broad categories:
Standard English Conventions
Expression of Ideas.
Each module begins with Standard English Conventions questions, which test the ability to form effective sentences in clear written English, using accurate grammar and punctuation.
After these, the module concludes with two questions within the Expression of Ideas category:
Transitions
Rhetorical Synthesis.
Types of Passages
Each SAT Reading and Writing passage is excerpted from some longer text and will be between 25 and 150 words. Passages encompass four subject areas: literature, history and social studies, humanities, and natural science. The genres of these passages range widely, from fiction, plays, and poems, to nonfiction essays and even student notes. But no outside knowledge is expected beyond the basic rules of English grammar and punctuation.
Moreover, test takers should not be overly concerned with the passage types. It’s far more important to recognize the question type associated with each passage, and to learn—and regularly practice—question-specific strategies.
III. Grammar and Usage Rules
The College Board further divides the Standard English Conventions questions in the SAT Reading & Writing section into two categories: (1) Boundaries and (2) Form, Structure, and Sense. Boundaries questions focus on how phrases, clauses, and sentences are linked together in standard written English. They primarily test how to link clauses and use correct punctuation. Form, Structure, and Sense questions focus on subject-verb agreement, pronoun-antecedent agreement, verb forms, modifiers, and how to correctly form plural and possessive nouns. Despite this division of grammar and punctuation questions into two categories, the questions will appear together, in no specific order, in this part of the test.
Boundaries
All Boundaries questions test the ability to construct sentences that are conventionally complete. That is, sentences that express complete thoughts, are structured in standard ways, and have appropriate punctuation. The most foundational concept for these questions is the clause: any group of words containing both a grammatical subject and a finite verb. More specifically, students should be able to distinguish between independent clauses and dependent clauses. An independent clause, as the name suggests, is simply a clause that can stand alone as a complete sentence. By contrast, a dependent clause has some feature that prevents it from standing alone as a complete sentence and instead must be connected to some other independent clause to function appropriately in standard written English. A dependent clause is often formed by adding a subordinate conjunction (e.g., “because” or “although”) to an otherwise independent clause, or else by having as its grammatical subject a relative pronoun (e.g., “which,” “that,” or “when”).
One of the most common writing-focused questions on the SAT involves recognizing that connecting two independent clauses requires using either a period or semicolon (which are functionally equivalent in this case) or a comma plus one of the seven coordinating conjunctions (FANBOYS). When two independent clauses are connected without a punctuation mark, this is called a run-on sentence. And when they are connected with a comma (but without a coordinating conjunction), this is called a comma splice. In addition, students should know when and whether to use commas to punctuate essential and nonessential elements, participial phrases, and compound predicates.
In addition to testing sentence-ending punctuation (periods and semicolons), SAT Boundaries questions cover colon and dash usage, two punctuation marks that many students find needlessly intimidating. With careful, intentional review of the rules for these punctuation marks, followed by disciplined practice with official questions, students should feel confident in approaching most Boundaries questions. Finally, questions in this category may test a student’s ability to correctly introduce quotations and to distinguish between instances where a punctuation mark is needed and those when, because the quotation is integrated into the sentence’s syntax, no additional punctuation is necessary.
Form, Structure, and Sense
The other category of SAT grammar and punctuation questions – those called Form, Structure, and Sense – focus on the rules that govern various parts of speech: nouns, verbs, adjectives, etc. Here, there are five common issues that students should know well if they are to score well on these questions:
SAT questions about subject-verb agreement typically appear within complex sentences, where the grammatical subject is separated from the main verb by several words, making errors more difficult to detect, so it’s crucial that, as soon as you recognize that a question is asking you to match a verb to its subject, you should carefully identify the subject in the passage, recognizing that the test makers have likely made this complicated. The SAT also tests nuanced issues such as compound subjects connected by "or" or "nor.” Here, the verb should agree with the last subject that appears in the sequence.
Pronoun-antecedent agreement is a crucial aspect of grammar, requiring that a pronoun align with its antecedent in both number and gender. Singular nouns must be paired with singular pronouns (e.g., "Everyone needs his or her book"), while plural nouns take plural pronouns (e.g., "Students finished their homework"). Ambiguity arises when pronoun references are unclear, leading to confusion about which noun the pronoun replaces. Indefinite pronouns such as "everyone" or "anyone" are always singular, despite their seemingly plural meaning. On the SAT, agreement errors frequently appear in longer sentences or those containing multiple pronouns, making it essential for students to ensure clear and consistent reference to antecedents to avoid confusion.
SAT questions on verb forms often test whether students can recognize consistent and logical tense relationships across sentences. A common trap appears when one verb in a sequence shifts tense without reason—for instance, from past to present—creating subtle inconsistency. The test also checks mastery of progressive and perfect forms, which express timing and completion. As soon as you note that answer choices involve different forms of a verb, verify the timeline of events: when did each action happen relative to the others? The SAT rewards precision, so make sure each verb accurately reflects sequence, duration, and consistency within its surrounding context. Questions about verb forms will often also test subject-verb agreement, so remember to identify the subject of each verb before you commit to an answer choice.
Questions about modifier placement often center on clarity and logic, specifically whether a descriptive phrase clearly and immediately refers to the word it’s meant to modify. On the SAT, a misplaced or dangling modifier can make an otherwise correct sentence appear subtly illogical. As you read, locate the descriptive phrase (often beginning with “which,” “who,” “having,” or “to”) and identify what it’s supposed to describe. Then check that this noun appears right next to the modifier. If not, expect an error. The rule of thumb: modifiers should sit as close as possible to the words they modify, and the sentence should make logical sense when read literally.
The SAT frequently tests a student’s attention to detail in distinguishing plurals from possessives, often in contexts where both forms are plausible. Apostrophes can change meaning entirely: students refers to multiple individuals, while student’s refers to one individual’s possession, and students’ signals something owned by a group. Questions may hide these distinctions within longer sentences, so when you see an apostrophe (or lack of one) changing among answer choices, slow down and ask: who owns what, and how many owners are there? Identifying that relationship correctly is key to choosing the right form.
IV. Expression of Ideas
The two questions that comprise the Expression of Ideas domain are Transitions and Rhetorical Synthesis, both of which test a student’s ability to express ideas in written English in a well organized, effective manner. These are always the last questions in any Reading & Writing module, coming immediately after the Standard English Conventions questions.
Transitions
Transition questions present a student with a short passage including a blank, where a transition word or phrase should appear. These questions often appear at the beginning of a sentence or clause and ask whether a connecting word or phrase (such as “however,” “therefore,” “meanwhile,” or “for example”) correctly expresses the relationship between the two parts of the passage. The student must choose from four options, selecting the one that best fits the structure of the passage. Here, the key challenge is that all the answer choices will seem grammatically fine. What matters is the meaning that best fits the given context.
As soon as you see an underlined transition, pause before looking at the answer choices and ask yourself a series of questions:
What is the basic idea presented before the transition? What is the basic idea presented after the transition?
What is the logical relationship between the ideas? Is it one of continuation or contrast? Is there a relationship of cause-and-effect, or temporal order?
What transition word or phrase would I choose to use here?
After making a prediction, turn to the answer choices and eliminate those that don’t fit the situation. To test any choice that remains, read the passage with the potential transition word and consider whether the relationship makes sense.
Rhetorical Synthesis
Rhetorical synthesis questions present a set notes, in the of bullet points, about a topic that will likely be unfamiliar to you. They then ask you to select an answer choice that most effectively combines information from the notes to achieve a specific writing goal.
Here, it’s important that your first step be to identify precisely what the instructions ask you to do. The instructions may look something like the following:
“The student wants to introduce the scientist and her field of study to a new audience”
“The student wants to make a generalization about the kind of study conducted by these researchers.”
“The student wants to emphasize a difference in the origins of the two words.”
Once you are clear about the goal you want to achieve, you should scan the answer choices, eliminating those that obviously don’t achieve this goal. Sometimes, you may find that you’re able to eliminate three incorrect answers without even consulting the notes. Other times, you’ll be able to eliminate two options, leaving you with just two choices to weigh against the given goal and the set of bullet points. If you’re struggling with time, you may find that comparing answer choices to the instructions given in the prompt is sufficient to identify the best answer choice. If you have a bit more time, then it’s wise to read the notes and confirm that your answer choice is the best before you move on to the next question.
Conclusion
Improving on SAT Writing questions comes from deliberate, repeatable process: predict first, choose the most concise grammatically correct option, then confirm logic, tone, and transitions. Treat core rules (agreement, pronouns, modifiers, punctuation, and parallel structure) like scales in music that you practice until they’re automatic. Track your recurring errors and rewrite them “the right way” to lock in patterns. Use Bluebook and other high-quality sets for targeted drills, saving a couple full tests for dress rehearsals.
