If you’re preparing for the SAT, the Writing & Language section can feel deceptively simple. After all, it’s “just English,” right? Not quite. The SAT isn’t testing your ability to write essays—it’s checking whether you can spot and fix grammar mistakes, improve clarity, and choose logical transitions. Many students lose easy points here because they fall into common grammar traps.
In this guide, we’ll cover the grammar rules and usage conventions that trip up test-takers most often, plus a diagnostic checklist for transitions.
1. Subject-Verb Agreement Traps
The Trap: Long phrases between the subject and verb.
-
Example: The bouquet of roses were lovely.
-
Correction: The bouquet of roses was lovely.
Tip: Always match the verb to the true subject, not the nearest noun.
2. Pronoun Ambiguity and Case
The Trap: Unclear pronoun references or wrong pronoun case.
-
Example: When a student studies hard, they should be rewarded.
-
Correction: When a student studies hard, he or she should be rewarded. (or use “students … they”)
-
Case Example: Him and I went to the library.
-
Correction: He and I went to the library.
Tip: Check if the pronoun clearly matches a noun and whether it’s subject (he, she) or object (him, her).
3. Modifier Placement
The Trap: Dangling modifiers.
-
Example: Running late, the homework was left at home.
-
Correction: Running late, I left the homework at home.
Tip: Place modifiers as close as possible to the word they describe.
4. Parallelism
The Trap: Lists that don’t follow the same grammatical pattern.
-
Example: She likes swimming, to run, and biking.
-
Correction: She likes swimming, running, and biking.
Tip: In comparisons and lists, make sure every element has the same form.
5. Punctuation Rules
-
Commas: Avoid comma splices (joining two sentences with just a comma).
-
Colons: Use to introduce a list or explanation—not randomly.
-
Semicolons: Only join two independent clauses, never a fragment.
6. Transitions: Diagnostic Checklist
Transitions are one of the trickiest parts of the SAT Writing section. Here’s a quick diagnostic test:
-
Does the sentence add new information? → Use furthermore, in addition, also.
-
Does it contrast with the previous idea? → Use however, on the other hand, nevertheless.
-
Does it show cause-effect? → Use therefore, thus, as a result.
-
Does it provide an example or restate? → Use for instance, in other words.
Trap: The SAT often gives you two correct-sounding options—but only one matches the passage’s logic. Always read a sentence before and after to see the flow.
7. Idioms and Usage
The SAT tests standard English usage:
-
Different from (not different than).
-
As…as comparisons.
-
Preposition precision: interested in, concerned with, responsible for.
Final Tips for Mastery
-
Practice with real passages: Don’t just memorize rules—apply them to SAT-style questions.
-
Eliminate obviously wrong answers: Even if two options look good, two are usually clearly wrong.
-
Trust logic over “what sounds right”: The SAT rewards grammar, not instinct.
