In a classroom, teachers move at the pace of the median student. With the answer key, you can move faster through chapters you dominate and slow down to analyze mistakes in chapters where you score below 80%.

By using this workbook, learners can develop a strong foundation in essential vocabulary and improve their overall language proficiency.

After checking the key, write two new sentences using "belied" and "exacerbated." Then, try to predict future test questions—for example, "The rain _______ our already difficult hiking conditions." (Answer: exacerbated).

If you’d like printable quizzes or worksheet versions keyed to this answer key (multiple choice, fill-in-the-blank, or matching), tell me the unit numbers and I’ll generate them.
