From the textbook's introduction: This book is to be used as a eight-week study guide. Each day, you will study three to four grammatical items found on the JLPT. Every week, from Day 1 to Day 6, you will study grammatical items which are similar in form and usage. On Day 7, you will check to see if you have learned them by doing the "Jissen Mondai" (Practice Test), that is in JLPT format. English translation is provided to explanations and examples sentences.
