Feeling a little overwhelmed by the SAT grammar rules? You’re not alone. The Digital SAT’s Reading and Writing section can feel like a puzzle, but we’re here to help you crack the code. The good news is that the SAT doesn’t test every obscure grammar rule in the book. Instead, it focuses on a core set of SAT grammar rules that are essential for clear and effective communication. By mastering these fundamental SAT grammar rules, you’ll not only boost your SAT score but also become a more confident writer.
Key Takeaways / TLDR
- Focus on the fundamentals: The Digital SAT prioritizes core SAT grammar rules like subject-verb agreement, pronoun-antecedent agreement, and proper punctuation rules.
- Understand sentence structure: Learn to identify independent clause and dependent clause patterns to avoid common errors like sentence fragments and run-on sentences.
- Practice with purpose: Use practice tests to identify your weak spots and focus your prep on the SAT grammar rules that challenge you the most.
- Read carefully: The Digital SAT often uses tricky wording and sentence structures to test your attention to detail.
- It’s more than just rules: Mastering SAT grammar rules is about understanding how to communicate your ideas clearly and effectively.
The Digital SAT Reading and Writing Section: What to Expect
The Digital SAT has a combined Reading and Writing section, which means you’ll see grammar questions mixed in with reading comprehension questions. The grammar questions on the Digital SAT are designed to test your understanding of Standard English conventions. These are the SAT grammar rules that govern how we write, from punctuation rules to sentence structure. The College Board wants to see that you have a solid grasp of the grammar skills needed for college-level writing.
Subject-Verb Agreement: The Foundation of a Strong Sentence
One of the most important SAT grammar rules is subject-verb agreement. This means that a singular noun must have a singular verb, and a plural noun must have a plural verb. It sounds simple, but the SAT can make it tricky.
- Singular Subject: The cat sits on the mat.
- Plural Subject: The cats sit on the mat.
The SAT often tries to confuse you by placing a prepositional phrase between the subject and the verb.
- Incorrect: The box of chocolates are on the table.
- Correct: The box of chocolates is on the table.
In this case, the subject is “box,” which is a singular noun, so the verb should be “is,” not “are.” Don’t let the plural noun “chocolates” in the prepositional phrase fool you! This type of subject-verb agreement challenge appears frequently on practice tests.
Pronoun-Antecedent Agreement: Keeping Your Pronouns in Check
Another key grammar rule is pronoun-antecedent agreement. A pronoun is a word that takes the place of a noun (e.g., he, she, it, they). The antecedent is the noun that the pronoun refers to. The pronoun must agree with its antecedent in number and gender.
- Singular: The student forgot his homework.
- Plural: The students forgot their homework.
A common mistake is using a plural pronoun with a singular antecedent within the same sentence.
- Incorrect: Every car should have their oil changed regularly.
- Correct: Every car should have its oil changed regularly.
Pay close attention to the noun that the plural pronoun refers to in order to ensure you have the correct pronoun-antecedent agreement.
Verb Tense: More Than Just Past, Present, and Future
Verb tense is another important aspect of SAT grammar rules. The verb tense tells you when the action in a sentence is happening. The SAT will test your ability to use the correct verb tense and to maintain consistent verb tense throughout a passage.
- Past Tense: I walked to school yesterday.
- Present Tense: I walk to school every day.
- Future Tense: I will walk to school tomorrow.
The Digital SAT also tests more complex verb tense forms, such as the present perfect and the past perfect.
- Present Perfect: I have walked to school many times. (used for an action that started in the past tense and continues to the present)
- Past Perfect: I had walked to school before it started to rain. (used for an action that happened before another action in the past tense)
Understanding verb tense consistency is crucial for creating a complete sentence that flows naturally.
Punctuation Rules: The Traffic Signals of Writing
Punctuation rules are a big part of the SAT Reading and Writing section. Here are some of the most important punctuation rules to know:
Commas
Commas have many uses, but here are some of the most common ones tested on the SAT:
- Separating items in a list: I need to buy milk, eggs, and bread.
- Setting off non-essential clauses: My brother, who is a doctor, lives in another state.
- After an introductory phrase or clause: After the movie, we went out for ice cream.
One of the most common comma errors is the comma splice. A comma splice occurs when you use only a comma to connect two independent clause structures.
- Incorrect: I went to the store, I bought some milk.
- Correct: I went to the store, and I bought some milk.
- Correct: I went to the store; I bought some milk.
- Correct: I went to the store. I bought some milk.
Semicolons
Semicolons are used to connect two closely related independent clause structures.
Example: I have a big test tomorrow; I can’t go out tonight.
Colons
Colons are used to introduce a list, an explanation, or a quote within a complete sentence.
Example: I need to bring three things to the test: a pencil, a calculator, and a photo ID.
Sentence Structure: Building a Better Sentence
The SAT will test your knowledge of sentence structure in a few different ways. You’ll need to be able to identify and correct common errors like sentence fragments, run-on sentences, and misplaced modifiers to create each complete sentence properly.
Sentence Fragments
A sentence fragment is an incomplete sentence that is punctuated as if it were a complete sentence. Often, these fragments contain a dependent clause without an independent clause.
- Incorrect: Because I was running late.
- Correct: Because I was running late, I missed the bus.
Run-On Sentences
A run-on sentence occurs when two or more independent clause structures are joined without proper punctuation or a conjunction.
- Incorrect: I love to write papers I would write one every day if I had the time.
- Correct: I love to write papers, and I would write one every day if I had the time.
- Correct: I love to write papers. I would write one every day if I had the time.
- Correct: I love to write papers; I would write one every day if I had the time.
Misplaced and Dangling Modifiers
A modifier is a word or phrase that describes another word or phrase. A misplaced modifier is a modifier that is placed in the wrong part of the sentence, so it appears to modify the wrong thing. A dangling modifier is a modifier that doesn’t have a clear word to modify.
- Misplaced Modifier: I saw a dog on the way to the store that was chasing a cat. (Is the store chasing a cat?)
- Correct: On the way to the store, I saw a dog that was chasing a cat.
- Dangling Modifier: Walking down the street, the trees were beautiful. (Were the trees walking down the street?)
- Correct: As I was walking down the street, the trees were beautiful.
Parallel Structure: Keeping Your Sentences Balanced
Parallel structure is another important grammar rule to know for the SAT. Parallel structure means that items in a list or series should be in the same grammatical form within the same sentence.
- Incorrect: I like to run, swimming, and to ride my bike.
- Correct: I like running, swimming, and riding my bike.
SAT Grammar Tips for Success
- Read the entire sentence: Don’t just focus on the underlined portion. The context of the complete sentence is often necessary to determine the correct answer.
- Eliminate wrong answer choices: If you’re not sure what the correct answer is, try to eliminate the answer choices that are clearly wrong.
- Trust your ear: If a sentence sounds awkward or clunky, there’s a good chance there’s a grammar error.
- Don’t be afraid to choose “NO CHANGE”: If the original sentence is grammatically correct, “NO CHANGE” will be the correct answer.
- Use practice tests strategically: Regular practice with official materials helps you recognize patterns in how these SAT grammar rules are tested.
- Sign up for our SAT test prep: On average, our SAT prep students see a 200-point increase in their SAT scores.
