① Book Introduction
This book is the revised 2nd edition of 'Cepheid 2F Chemistry (Part 1) (979-11-92982-02-1)', with more precise content and richer commentary.
The Cepheid Science Series—Infinite Imagination—consists of six stages: Middle School Basics (1F), Middle School Completion (2F), High School Completion 1 (3F), High School Completion 2 (4F), Practice Problem Solving (5F), and five mock exams, the first in Korea to refine middle and high school science and creativity problems. Now you can enjoy studying science with ease.

1F Middle School Basics: Students who are new to science.
People who want to learn science step by step.
People who want to develop creativity from the ground up
2F Middle School Completion: Those who want to complete middle school science and master middle school level creativity.
3F Advanced Completion 1: For those who want to complete High School Science 1.
People who want to develop high-level creativity
4F Advanced Completion 2: Those who want to complete high school science 2 and master advanced level creativity.
5F: Solving practical problems: Those who want to prepare for each exam and competition through advanced problems, in-depth problems, and convergence problems.
Mock Exam: The final step to test your creative problem-solving skills.

Ultimately, it's about creativity.
Creativity is the ability to come up with something useful and new.
Elements of creativity include originality in expressing one's own opinion, flexibility in showing connections with other topics, fluency in expressing multiple opinions, sophistication in expressing more accurate and detailed opinions, and sensitivity in expressing sharp and quick opinions.
Meanwhile, various entrance exams and competitions measure and evaluate creative problem-solving skills.
STEAM education, which has recently become the biggest issue in the education world, aims to foster creative convergence talents by integrating science, technology, and the arts, fields that have been viewed separately.
The Creativity Science Cepheid series enhances scientific creativity.

② Book Features
(1) Lecture: The content of one unit is divided into four sections and organized.
The concepts are clearly organized and it is a very good format for lectures.
(2) Concept confirmation, confirmation+, concept reinforcement: This is composed of problems that can be easily solved and the content organized using the lecture content.
(3) Type Mastery & Havruta: The content of related units is divided into types, and representative problems and practice problems are provided for each type so that problems can be solved through discussion.
(4) Creativity & Discussion Forum: By presenting a wealth of creativity problems related to the content of the relevant sub-units, we have improved creativity while also allowing for natural questions to be raised and discussions on related topics to be possible.
(5) Self-improvement of skills: A sufficient number of review problems and assignments for what has been learned are provided at each level.
It is provided in ABC-advanced stages, allowing you to improve your skills by difficulty level.
(6) Project: At the end of each unit, reading materials on the topic were provided to answer descriptive/argumentative questions, and key experiments for each unit were presented to enable individual implementation.
STEAM activities will be possible as convergent problems are presented together.

This book
(1) We provided ample opportunities for creative problem solving to students preparing for research and creativity oral examinations and interviews at science high schools, gifted schools, and specialized high schools.
(2) For students preparing for various competitions or secondary gifted education centers, we provided questions from previous exams, including those at the secondary chemistry level and above.
(3) For students who want to prepare for middle school exams, we provide a variety of problems at various levels to help them fully understand the principles and achieve perfect scores on the exams.
