This book focuses on the reading comprehension for level 2 of the JLPT.
In the first part, the student must fill in the blanks of a text (multiple choice). What's difficult about this part is that students need to know the sentence structure according to Japanese grammar.
The second part is all about reading comprehension. It starts with short texts that become gradually longer.
The third part is about reading, too, but in this case students will be required to filter relevant information from a text.
The difficulty becomes increasingly higher in each of the three levels.
