Get ready to ace your SAT with these essential grammar... Show more











Tomorrow's SAT exam requires strategic preparation to maximize your score. This review session focuses on key grammar rules and question types you'll encounter on the test.
During this practice session, we'll examine common SAT grammar challenges and work through multiple-choice questions together. By analyzing these examples, you'll develop the critical thinking skills needed to select correct answers confidently.
Pro Tip: The SAT Writing section tests specific, predictable grammar rules. Mastering these rules now will give you a significant advantage during tomorrow's exam!

The SAT commonly tests your ability to select the correct word based on context. One major category is homophones—words that sound identical but have different meanings and spellings.
Common homophones tested include fare/fair, cite/sight/site, then/than, there/their/they're, and its/it's. For example, in the sentence "More like a fair than an actual café," you need to recognize that "fair" (exhibition) is the correct noun and "than" is the correct comparative word (not "then," which relates to time).
When tackling these questions, always consider the specific meaning of each word option and how it functions in the sentence. Reading the sentence aloud can sometimes help you catch these subtle distinctions.

The second type of word choice question involves selecting between related words or synonyms where only one fits the precise context of the sentence.
For example, in "officials recently _____ original paintings to be made," your options might include decreed, commissioned, forced, and licensed. Though similar, "commissioned" is the only appropriate choice because it specifically means hiring an artist to create artwork.
To prepare for these questions, focus on understanding subtle differences between related words. Practice identifying which word conveys the precise meaning needed in each specific context—this skill comes from developing a nuanced vocabulary.

The SAT rewards concise writing that avoids redundancy. Generally, the shortest grammatically correct answer that conveys the complete meaning is correct.
Watch for phrases like "annually every year" or "personally for me" where words unnecessarily repeat the same idea. In the example "other countries on top of that," the phrase "on top of that" is redundant and should be deleted since "and other countries" already completes the list.
Remember: When all answer choices convey the same information, the most concise option is typically correct. The SAT values clarity through brevity!

Idiomatic expressions are phrases that follow specific patterns in standard English. These questions often test whether you can identify the correct preposition to use with a particular verb or phrase.
Common examples include "focus on" (not at), "as a means of" (not through), and "in accordance with" (not to). There's no formula for these questions—they test your familiarity with standard English conventions.
The best way to prepare for idiom questions is to study examples from practice tests and develop an ear for proper English usage. Native speakers often get these questions right by what "sounds correct," but international students may need to memorize common idiomatic phrases.

Verbs in a sentence should maintain consistent tenses unless there's a logical reason to shift time frames. The SAT frequently tests your ability to identify when verbs should stay in the same tense.
For example, "Last week, Frank rented a car and drives to Las Vegas" contains an error because "drives" should be "drove" to match both the past tense "rented" and the time marker "Last week."
Pay special attention to surrounding sentences, as they often provide context clues for which tense is appropriate. When you see an underlined verb on the test, quickly check if it matches the established time frame of the passage.

The SAT tests whether you know how to properly use commas with non-restrictive clauses and appositives—elements that add information but could be removed without changing the core meaning of the sentence.
Non-restrictive clauses (often beginning with "which" or "who") should be surrounded by commas: "Joe's parents, who constantly call him, are very overprotective." The clause provides extra information but isn't essential to identifying which parents are being discussed.
Similarly, appositives (descriptive phrases without verbs) need commas: "Val, a Wisconsin native, loves fried cheese curds." The appositive adds detail about Val but isn't necessary to the sentence's basic meaning.

A comma splice occurs when two independent clauses (complete thoughts) are joined only by a comma. This creates a grammatical error called a run-on sentence.
Incorrect: "Ken likes Selena Gomez, she is his favorite singer." Correct options include:
Quick Test: If both parts of the sentence could stand alone as complete sentences, a comma alone is not enough to join them!

Semicolons function like periods; they separate two independent clauses. The key rule: both sides of a semicolon must be able to stand alone as complete sentences.
Incorrect: "Because Teresa wanted to please her family; she became a doctor." Correct: "Teresa wanted to please her family; she became a doctor."
Avoid placing semicolons after dependent clauses or phrases. In the SAT example, "Living independently and demonstrating an intense work ethic; the Harvey Girls..." contains an error because the first part isn't a complete thought.
When you see a semicolon on the test, mentally replace it with a period and check if both parts could be separate sentences—if not, the semicolon is incorrect.

A colon must be preceded by an independent clause (complete thought). Colons are typically used to introduce lists, explanations, or elaborations.
Incorrect: "Meena enjoys multiple genres of music like: alternative, rap, heavy metal, and country." Correct: "Meena enjoys multiple genres of music: alternative, rap, heavy metal, and country."
The first example is wrong because "Meena enjoys multiple genres of music like" isn't a complete thought. When you see a colon on the test, check if you could end the sentence at that point and still have a grammatically complete statement.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️
