It was great to be able to quickly study the written exam material for the Big Data Analysis Engineer certification through the course~ Thank you.

What you will gain after the course

  • Completed one full review of all four subjects (4 hours 45 minutes of video / 20 lectures total)

  • Experience solving 5–20 modified past exam questions for each section

  • Two 150-page lecture material PDFs (without questions / with questions)

  • 13-Page Test Site Final Notes

  • The cutoff for avoiding failure (40 points) in subjects you lack confidence in

The 13th written exam (9/5) has ended.
The information below is based on the next exam session.

  • Announcement of the 13th written exam results: September 23 (Wednesday)

  • 14th Written Examination: Scheduled for the first half of 2027 (schedule not yet announced; the written exam in the first half of each of the past two years was held on the first Saturday of April)

  • This course is dedicated exclusively to the written exam.

The written exam consists of 80 multiple-choice questions / 120 minutes / 4 subjects, at least 40 points in each subject + an average of at least 60 points means you pass the exam.
Scoring below 40 points in even one subject results in failure.
What you need right now is not a perfect understanding, but preventing subject failure and scoring an average of over 60 points.

This course has no expiration date, so you can go through it once now and review it again when you register for the exam.

I bought the book, but
I don't know what I should memorize.

The written exam for the Big Data Analyst Engineer certification covers a wide range of topics, including statistics, data analysis, modeling, and laws and regulations.
As a result, most test takers spend more time determining what is important than actually studying.

A 32-hour all-in-one course is a good option when you have plenty of time, but
if the exam is just around the corner, 32 hours of a course you cannot finish is the same as 0 hours.

This course quickly brings you up to the level needed to solve exam questions and prepares you through practice problems..

✏️ Written exam study tip

  • For the written exam, it is a concept-memorization format, so the most efficient approach is to thoroughly read one core textbook and then repeat past and expected questions.

  • Since terminology, methodologies, and statistical concepts appear repeatedly, it is helpful to create a separate note of confusing terms.

  • The key is to avoid failing a subject (scoring below 40 points)! Even in subjects you’re not confident in, focus on past exam questions to secure the minimum score.

What You’ll Take Away After Completing the Course

  • I explained the Big Data Analysis Engineer terminology as simply as possible so that even non-majors can understand it.

  • I believe the purpose of taking a course is to save time. We create and explain easy-to-understand examples so you can finish in just four hours.

About the knowledge sharer

A master’s degree holder in statistics and government-funded data analysis instructor
I’ve included only what appears on the exam.

I passed the exam myself and have actually taughtthis based on my experience.

"As someone who has also studied statistics and data analysis for a long time, I understand how difficult familiar concepts can feel to someone encountering them for the first time. That's why, rather than conveying professional terminology as-is, this course focuses on rephrasing it in a way that even first-time learners can understand."

Curriculum

Course-by-course curriculum matching at a glance

We’ll give you the honest truth.

I do not recommend this for people who...

From taking the course to intensive preparation before the exam
, we provide three types of materials..

1️⃣ Approximately 150-page PDF

We provide study materials that organize the lecture content for easy reference.

2️⃣ Subnotes for last-minute exam review

Review quickly right before the exam with a 13-page supplementary note.

3️⃣ Modified past exam questions by section

Practice applying what you’ve learned to real problems by solving 5–20 questions for each section.

Frequently Asked Questions

Q. If I start now, can I finish watching everything before the exam?
The total video length is 4 hours and 45 minutes. You can complete one full run-through in two days by studying for 2 hours each day. Just follow the D-day plan above.

Q. I’m not a statistics major and don’t know anything about statistics.

No prior knowledge is required. We explain everything with diagrams and examples, starting with the basics such as the mean and median. First, check the difficulty level with the free “Summarizing Data Characteristics Numerically” lecture.

Q. Can I also prepare for the practical exam with this course?

No. This course is for the written exam only. The practical exam is a Python coding-based CBT, so separate preparation is required.

Q. Is passing guaranteed if I only take this course?

To be honest, no exam can guarantee passing with concept lectures alone. The role of this course is to get you ready to solve past exam questions and CBT questions in the shortest possible time. We also help you connect the concepts to each section through modified past exam questions.

Q. How do I receive the materials?

They can be downloaded directly from Section 1. You will receive everything immediately after payment: two versions of the lecture materials PDF (without and with questions), question and answer explanations, and a final review note for the exam day.


No one has enough time to study perfectly.

You need to decide exactly what to study now.

No matter when the exam is, you can finish your first pass through all four subjects in just two days.
You can also check it out first with the four free preview lessons.

Who is this course right for?

  • Those who narrowly failed this session due to not meeting the minimum score in one subject and are preparing for the next session

  • Those who want to get an overview of all four subjects before enrolling

  • Those who want to quickly complete one review of the concepts before starting the basic textbook and question bank

Need to know before starting?

  • None. This is explained for non-majors encountering statistics and data analysis for the first time.

  • However, preparing for the practical exam (Python) is outside the scope of this course.
