A new addition to the highly acclaimed 'From Not Understanding to Understanding' series—renowned as an ultra-fundamental problem book for mastering basics—this book is perfectly tailored for adults seeking to relearn English. It is a textbook designed to relearn 'junior high school English' in just 30 days with 30 minutes of study per day using a 3-step method, transforming knowledge into 'usable English'.

Step 1: Memorize – Grammar Explanation Pages

Focused on English grammar taught in junior high school, this section consists of grammar explanations and practice exercises.

The grammar explanations, like those in the popular 'From Not Understanding to Understanding' middle school reference series, use clear illustrations and explanations to help grasp key points. All basic sentences and questions come with audio support.

Practice exercises allow users to check their understanding of the explanations, ensuring steady mastery of grammar points. Answers are printed at the bottom of the same page, enabling a smooth flow from learning to problem-solving and answer checking.

Step 2: Internalize – Audio Review

Key grammar points learned in Step 1 can be solidified through rhythmic chants. By repeatedly speaking English aloud to the fun rhythm of chants, English naturally starts flowing from the mouth.

After input in Step 1, Step 2 enables output practice, bringing learners one step closer to 'usable English'.

Step 3: Internalize – Improvisational Training

Based on content learned in Steps 1 and 2, learners can practice conversations through improvisational training—the final stage of output. With a two-page spread format, conversation practice is on the left page, and answers are on the right page for immediate review.

Conversation practice is set in everyday scenarios, allowing learners to translate Japanese parts into English or role-play characters speaking in English, thereby developing 'speaking ability'.

Additionally, self-expression exercises and vocabulary sections related to conversation scenes further build speaking skills, transforming English knowledge into practical, usable language.
