The Last SAT Punctuation Guide You’ll Need
James Lu SAT
Overview
This video provides a comprehensive strategy for mastering SAT punctuation questions, aiming for 100% accuracy in under 10 seconds per question. It breaks down the process into identifying independent clauses, understanding the six key punctuation marks (colon, period, semicolon, comma, dash, parenthesis), and applying a specific problem-solving algorithm. The guide emphasizes recognizing patterns, prioritizing answer choices, and utilizing shortcuts like title-name rules to efficiently tackle various question types, ultimately boosting test-taking speed and accuracy.

Chapters
- An independent clause requires a subject and one main verb.
- The subject is typically found at the beginning of the clause.
- Main verbs are the primary action performed by the subject; verbs with '-ing' endings, infinitives ('to' + verb), or verbs within extra information/noun phrases are generally not main verbs.
- An independent clause cannot begin with a dependent clause starter (e.g., 'when,' 'although').
Correctly identifying independent clauses is fundamental because most punctuation rules on the SAT revolve around how these clauses connect or are modified.
In 'The boy who ran across the street fell,' 'fell' is the main verb because it's the primary action the subject ('the boy') performs, while 'ran' is part of an extra descriptive phrase.
- Colon (:): Requires an independent clause before it, followed by an 'expanding dot' that elaborates on the preceding clause.
- Period (.): Separates two independent clauses.
- Semicolon (;): Can either separate two independent clauses (like a period) or be used in lists where items themselves contain commas (semicolon list).
- Comma (,): Used to set off non-essential elements (additional information) or in lists of three or more items. Crucially, a comma should not precede the word 'that' when 'that' introduces an essential element.
- Dash (—): Can set off non-essential elements (like a comma, but requires a matching dash sandwich) or, less commonly tested, replace a colon.
- Parenthesis (()): Encloses additional, non-essential information, functioning similarly to commas or dashes for non-essential elements.
Understanding the specific function and placement rules for each of these six punctuation marks is crucial for correctly constructing sentences and identifying errors on the SAT.
For a colon, 'I saw three colors: yellow, red, and violet' is correct because 'I saw three colors' is an independent clause, and the list expands on 'three colors'.
- Comma + FANBOYS (For, And, Nor, But, Or, Yet, So): Functions identically to a period or semicolon in connecting two independent clauses.
- Semicolon Lists: Use semicolons to separate items in a list if those items already contain commas, ensuring clarity.
- Title-Name Rule: No punctuation is allowed between a title (e.g., 'astronaut') and the name it modifies (e.g., 'Buzz Aldrin') if they form a single phrase.
- Transition Words: Words like 'however' or 'therefore' that connect sentences are non-essential elements and require punctuation (usually commas) before and after them if they appear mid-sentence.
Recognizing specific question types and applying shortcuts allows for faster elimination of incorrect answers and quicker identification of the correct punctuation.
If a sentence contains 'astronaut Buzz Aldrin,' no punctuation should appear between 'astronaut' and 'Buzz Aldrin' because they are part of the same descriptive phrase.
- Prioritize answer choices based on likelihood of correctness, not their order (A, B, C, D).
- The priority order is generally: Colon (highest priority), then Period/Semicolon/Comma+FANBOYS, then Isolated Comma, and finally No Punctuation.
- This strategy is derived from analyzing the frequency of correct punctuation usage on official SAT tests.
- When multiple punctuation marks (like period, semicolon, comma+FANBOYS) perform the same function (linking independent clauses), they are often interchangeable, allowing for elimination if they appear in the same spot.
This systematic approach significantly speeds up the process of answering punctuation questions by focusing on the most probable correct answers first, saving time and reducing errors.
If an answer choice offers a colon, check that option first before considering others, as colons are highly likely to be correct when used properly.
Key takeaways
- Mastering the identification of independent clauses is the foundational skill for all SAT punctuation questions.
- Understand that periods, semicolons, and comma+FANBOYS can often be interchangeable when linking two independent clauses.
- Colons are primarily used when an independent clause is followed by an elaboration or list that expands on it.
- Commas are essential for setting off non-essential information but should not precede the word 'that' when it introduces essential information.
- Dashes function similarly to commas for non-essential elements but require a 'dash sandwich' (an opening and closing dash).
- The 'Title-Name' rule is a critical shortcut: no punctuation should separate a title from its corresponding name within the same phrase.
- Prioritizing answer choices based on statistical likelihood (e.g., checking colons first) is a powerful time-saving strategy.
