SAT Form, Structure, and Sense

Form, Structure and Sense covers agreement and verb form: subject–verb agreement, pronoun agreement, verb tense, and modifier placement. Most questions hinge on identifying the true subject, which the sentence usually separates from its verb with an intervening phrase.

FAQ

Form, Structure, and Sense questions

How do I find the subject of a long SAT sentence?

Strip out prepositional phrases and clauses between the subject and the verb. The noun left standing is the subject — not the plural noun sitting nearest the verb.

Does the SAT test tricky grammar rules?

No. It tests a small set repeatedly: agreement, tense, pronouns and modifiers. The difficulty comes from sentence length, not from obscure rules.
