There are seven units, and each consists of ten lessons, including a feature lesson called "The Grammar Games." The Power Drill Book aims to combine enjoyment with learning, on the principle that grammar can be the most enjoyable class, not the least enjoyable, of a student's (and teacher's!) subjects.

What makes The Power Drill Grammar Book unique? It's fun. It's practical. The sample sentences are in step with modern times (computers, video games, etc.). Most importantly, the grammar is simple, clear, up-to-date -- and it's focussed on esl students' primary needs: error correction of their writing and speech, and expansion of their range of expression. Teaching grammar is a pleasure using these materials!
