In The Winston Grammar Program learning is incremental, with each lesson building upon previously-learned materials. All lessons after the first, therefore contain some built-in review. Most lessons introduce a new concept stated as a focus on a particular part of speech; however, some lessons are entirely review work. The student workbook includes a pre-test, post-test, quizzes and 30 individual lessons. This workbook is set up exactly as the Basic Level workbook (Stock #24685), but the sentences are different. This book is intended for further practice after finishing the Basic Level workbook. Pages are perforated for easy removal. This package also includes an answer key.
