Helpful SAT Grammar Tips

The SAT is split into three sections: evidence-based reading & writing, math, and an optional essay.

So, to ace this part of the test, take a look at some helpful SAT grammar tips that will prepare you for any reading and writing questions that come your way.

Understand Vocabulary in Context

Knowing how to assess a word’s meaning in relation to the context of the passage is a huge part of the reading & writing section. There will be multiple-choice questions that ask you to replace a word within a sentence with a better option that makes more sense. Using context clues, you’ll have to select the choice that improves the sentence.

The Subject and Verb Need to Agree in Number

In a sentence, the subject and the verb must always agree in number—so, if the subject is singular, the verb must be singular, and vice versa. Likewise, if the subject is plural, the verb must be plural, and vice versa.

Singular example: Jerry talks to clients. Jerry is a singular subject, and talks is a singular verb.

Plural example: Jerry and Tara talk to clients. Jerry and Tara is a plural subject, and talk is a plural verb.

To make matters more complicated, subjects can also be collective nouns. These are “group words” that refer to a single subject (they are singular). For instance, these are words like family, choir, class, jury, and staff. So, when a collective noun is the subject of a sentence, it should be paired with a singular verb.

Ensure Consistent Verb Tense

You also need to make sure that the tense is consistent throughout the sentence.

Correct example: Emily parks the car, walks into the store, and opens the freezer.

Incorrect example: Patrick likes climbing rocks, writing blogs, and walked his dog.

Detect Comma Splices

A comma splice is when two grammatically complete sentences are combined with a comma. Make sure that you can detect and eliminate all comma splices. These can be tricky and easy to overlook!

Example comma splice: It’s hot outside, let’s go to the beach.

Correction: It’s hot outside. Let’s go to the beach.


Correction: It’s hot outside; let’s go to the beach.


Correction: It’s hot outside, so we should go to the beach.

Identifying Fragments and Run-On Sentences

Finally, make sure you’re on the lookout for run-on sentences and sentence fragments. A subject and a predicate (a clause) must be present and connected with correct punctuation to be considered a complete sentence. As we saw in the previous rule, the subject and predicate must be connected by a comma, a semicolon, or a conjunction.

Run-on example: Danny works on computers he works on them every day.

Correction: Danny works on computers. He works on them every day.

Fragment example: Jess talking to clients and taking notes.

Correction: Jess is talking to clients and taking notes.
