Why Use This Tool

The SAT Writing & Language test focuses heavily on grammar, clarity, and sentence structure. Most mistakes happen because students rush or overlook rules they “kind of” remember. This tool helps you fix weak spots by showing instant feedback so you learn the grammar concepts the SAT uses repeatedly.
How to Use It
  • Practice each sentence correction or grammar question.
  • After answering, review the explanation to understand why the correct answer works.
  • Pay attention to repeated patterns (comma use, subject–verb agreement, pronoun clarity).
  • Return often for quick refreshers, especially before writing-related modules.
