SAT Punctuation Guide: Commas, Colons, and Dashes Explained

Welcome to our lesson on mastering comma usage for the SAT!Let's start with the first rule: using commas to separate items in a list.Notice how commas separate each item, with an optional Oxford comma before 'and' in the first example.Our second rule involves coordinating conjunctions, commonly remembered as FANBOYS.When joining two complete sentences with these conjunctions, we need a comma before the conjunction.The third rule covers non-essential clauses, which are set off by commas and can be removed without changing the sentence's core meaning.Notice how the sentence still makes sense when we remove the clause between the commas.Let's look at a typical SAT practice question testing these rules.Option B is correct because it properly sets off the non-essential clause 'who won the award' with commas.Colons serve two primary functions in formal writing: introducing lists and connecting related ideas.For the first rule, a colon can follow a complete sentence to introduce a list.
