This book has been designed to prepare the reading and grammar part of JLPT level 3 and is divided into 3 parts.
In the first part, students must fill in the blanks in a text (multiple choice). What's tricky about this part is that students must know the sentence structure according to Japanese grammar. Since all answers are very similar, students should choose the most logical one.
The second part is about reading comprehension. It starts off with short texts that get longer progressively.
The third part is all about reading, too, but in this part students must learn how to filter relevant information.
In each of the three parts of this book, the difficulty increases gradually.
