Course Wrap-Up

Master the six grammar systems the TOEFL actually tests: sentence cores, complex clauses, tense and voice, parallelism, modifiers and punctuation, and academic transitions — with a quiz after every section and a 5-question comprehensive grammar audit.

The TOEFL isn't a grammar test — but grammar is graded in every Writing and Speaking
response, and it's the hidden skill behind Reading's Sentence Simplification questions. This module gives you the six grammar systems that matter most: sentence cores, complex
clauses, tense and voice, parallelism, modifiers and punctuation, and academic
transitions — each with one clear rule, one real example, and the trap ETS builds around
it.
