I was a first-year student in a related major, so I was practically like a non-major, but I studied hard with this summary + old past exams (rounds 1-14), and by discarding what needed to be discarded, I passed in just one month!!

I'm a non-major. I passed after just a month and a half of studying with the renewed book. However, I really recommend that you somehow get a hold of past exam question books and study them together.

Digital Forensics Expert Exam,
Isn't there a more efficient way to study?
🫥 "I want to pass the exam, but I don't want to study hard."
😀 "I want to quickly memorize only the key content that will be on the exam and pass comfortably."
Everyone preparing for an exam thinks this way. The passing score for the Digital Forensics Expert Level 2 written exam is 60 points. Those who score above 60 points pass, and those who don't, fail.
Learning new material is not easy. In particular, spending precious time on content that won't even appear on the exam is extremely inefficient. Some people give up on the exam after becoming frustrated while trying to study meticulously from the beginning, while others only study the earlier sections and fail the exam without covering the important later parts.
I was the same way. I wanted to study as efficiently as possible and pass with over 60 points in a short period without struggling. That's why I decided to create this course.
"I will provide you with a ladder to comfortably climb over the high wall of the exam"
Digital Forensics Expert Level 2 Exam? 🤔
The written exam consists of a total of 5 subjects. Since each subject requires knowledge across the entire field of computer engineering, the scope is very broad and there is a lot to study. Additionally, the difficulty level of the exam questions is similar to that of the Information Processing Engineer and Information Security Engineer exams, making them quite challenging.
In particular, the Digital Forensics Introduction section is the most important part, accounting for 40% of this exam. This field is not covered in any other exam, and difficult questions that can only be answered through practical experience, beyond theoretical knowledge, are also being asked. Without strategic preparation, you could end up spending an enormous amount of time dealing with the broad content across 5 subjects and the high level of difficulty.
Instructor Introduction 👌
I obtained the Digital Forensics Expert Level 2 certification in 2022.
My Inflearn course "Digital Forensics from the Basics" achieved a 5.0 rating and 1,900 students in 9 months.
Course Introduction 💡
This course introduces the exam trends for the 5 subjects of the Digital Forensics Expert certification and summarizes the key content in an easy-to-understand manner.
For those who purchase this course, an additional lecture on study methods is provided free of charge. The free lecture introduces an overview of the Digital Forensics Expert Level 2 written exam and the characteristics of each subject. It also provides learning strategies for the written exam and specific study methods divided into cases for non-majors and majors.
📢 Please check before enrolling!
- This course is a text-based lecture, and a PDF file of approximately 170 pages will be provided.
Course Features ✨
#1.
Reduce
study time
Typically, to prepare for the exam, you need to study all 5 official textbooks from the testing organization. The total page count of these 5 books amounts to a whopping 1,300 pages.
"Difo Level 2 Written Exam Core Summary" has condensed only the essential content, reducing the study material to 170 pages. We've compiled only the core content so you can pass with this short 170-page textbook. The summary includes only concepts that appear in past exam questions, removing all unnecessary parts and containing only the essence. Content not found in the official textbooks has also been added to the summary if it appears in past exams.
I've compiled it into a single volume, removed all unnecessary parts, and included only the essential content. I've also added content to the summary that appears in past exams even if it's not in the official textbook.
#2.
Only Core Topics
Fast and Efficient
We've selected approximately 100 core topics from 5 subjects, focusing only on topics likely to appear on the exam. Nearly all content in this book consists of material that has appeared or could appear on the exam. It's systematically structured to help you efficiently exceed the passing score of 60 points.
#3.
Latest past exam questions and
trends included
We integrated all 5 sets of past exam questions into one summary, making it possible to prepare for the exam with just this single textbook. I am confident that repeatedly studying this one textbook will directly help you pass the exam.
#4.
Rich explanations
I created this textbook with the idea of "making it easy for non-majors to understand or memorize." I made efforts to provide detailed explanations as much as possible through comparisons and examples for parts that might be difficult to understand, and for terms that might be hard to memorize, I included English expressions alongside them to make memorization easier.
Study methods that even non-majors can pass with
Non-majors can pass within 1 month, and majors can pass within 1 week.
We introduce the easiest and fastest study method to pass the exam, even for non-majors and those who know nothing about digital forensics.
- Purchase the course and download the e-book.
- Refer to the study method described in the book and complete the first reading as quickly as possible.
- Read the book 3 times and memorize the key content.
- Check your skills by solving past exam questions.
- Pass the exam in the easiest and fastest way.
I am confident that studying this way will allow you to pass the exam most efficiently. Even non-majors can pass with 100% certainty within one month following this method. Those who have knowledge of digital forensics or basic knowledge of computer science can pass within one week. Study according to the study method and pass in the easiest and fastest way!
Pass the exam and advance your career
Through this course, you can pass the exam and obtain your certification. You can not only get a job in the digital forensics field, but also prove your expertise in the overall information security field. With this certification, you can succeed in both getting hired and changing jobs.
Imagine yourself passing the exam. You'll feel proud for passing the exam as a reward for your hard work.
Also, with the certification in hand, you'll be much more confident and self-assured than before.
Expected Questions Q&A 💬
Q. What is the difficulty level of the Information Processing Engineer Level 2 written exam?
The difficulty level is extremely high for non-majors to prepare for. In particular, subjects 1-4 (Computer Architecture, Operating Systems, Databases, and Application Programs) account for 60% of the exam, and those without relevant knowledge in these areas sometimes fail due to falling below the passing threshold (less than 40 points). When creating this e-book, the most important aspect I considered was, "What is the minimum knowledge that people without a major background need to know?" I want to help you study comfortably for this high-difficulty exam.
Q. When is the Difojeon Level 2 written exam scheduled for this year?
The Level 2 written exam is conducted twice a year. Once in the first half (April-May) and once in the second half (October-November). Considering the exam preparation period, we recommend starting about a month in advance. We are currently running a discount event to celebrate the course launch. The discount event will end soon, so please purchase quickly!
Q. Where can I use the DiForensic Level 2 certification?
The Digital Forensics Professional Level 2 certification is the only nationally recognized digital forensics certification in Korea. Previously, certifications issued by EnCase were commonly used for job changes and career advancement, but as it is no longer possible to obtain this certification domestically, the value of the Digital Forensics Professional Level 2 certification continues to increase. Since the exam scope for the Digital Forensics Professional Level 2 certification covers everything from theoretical content to practical work and legal matters, your digital forensics capabilities can be recognized, and it can help with employment and career transitions.
Q. Is the e-book continuously updated? Can I check the updated content?
The e-book is continuously updated, and you can download the latest version of the e-book through the link on the course page. Even if you have previously purchased the e-book, you can continue to download the latest version through the link.

100% enrolledTo get straight to the point, I mainly studied with this summary guide, and I passed the written exam, but I think this summary guide has some outdated parts 😭 When I studied with the summary guide and solved past exams (I only got relatively old past exams from before 2019 due to circumstances and only solved those), I thought it was well-summarized as the parts emphasized in the summary guide appeared frequently. Therefore, I went to the exam center having almost memorized the entire contents of the summary guide... But in the 2025 24th exam I took, there was very little content from the summary guide itself, let's say nothing of the content emphasized in the guide... 😭😭 I am a cybersecurity major, so I think I managed to pass by somehow pulling knowledge from the back of my mind, but when I first came out of the exam center, I felt so lost that I thought I would surely fail. If you are a major and already have some knowledge of forensics, I think it's not bad to get a feel for it with this summary guide, with the idea of rebuilding your conceptual framework, but for non-majors to study mainly with this summary guide and quickly pass the written exam just like that, I think this summary guide is now unsuitable...!

Hello! Thank you very much for leaving an honest review, and I apologize. After reading the details you provided in the review and giving it thought, I've decided to renew the e-book. Upon checking, 5 new textbooks were published in 2024, and it seems the overall exam trends have changed accordingly. Since the last update was in August 2023, I also missed the trend. To everyone reading this post, I promise a complete renewal of the e-book by around mid-July. I apologize and thank you.

100% enrolledIt's good to be aware of the pros and cons and make an informed purchase. Pros: - The content of a very long textbook is summarized, focusing only on the key points, making it easy to skim through the material in a short amount of time. - It's good for understanding exam trends and predicting frequently asked questions. Cons: - There are many typos and inaccuracies throughout. It doesn't seem like they update the typos promptly. - It doesn't cover 100% of the content that appears on the exam, so you can't get a perfect score by only studying this. You'll still need to buy and study the textbooks created by the Korean Association of Digital Forensics. Overall: It feels like looking at a college student's notes with important points highlighted. If you have no basic knowledge, it's not a bad idea to buy it and take a look.
