As students begin to seriously tackle problems, they may have been concerned about whether they were progressing in the right direction in their studies and the gap between theory and problem-solving.
This masterpiece of mock exams by progress level by Lee Geun-sang analyzed firefighting problems that had been tested for many years and divided the introduction to firefighting and firefighting-related laws into 8 parts (progress levels), and produced 25 problems for each part with difficulty levels of basic, fundamental, and advanced.

It is an efficient system that provides various types of problems, including short answer, application, and difficult problems based on understanding and principles, along with detailed explanations and readings of related theories.
The test paper is organized into sections to make it easy to organize error notes and single-volume books, and the commentary book, which is organized into books within a book so that it can be used as feedback, is a test preparation book with many potential uses.
This is a study guide that allows students preparing for exams to check their strengths and weaknesses, fill in their weaknesses, and build on their strengths to become stronger and more resilient.
I hope that you will make the most of Lee Geun-sang's "Masterpiece" mock exams by level, increasing your problem-solving adaptability and serving as a stepping stone to further develop yourself.
