What is the Big Data Analysis Certification Squid Game?


This is a mission-based challenge to prepare for the Big Data Analysis Certification practical exam.
By completing daily missions, you will repeatedly train through processes similar to the actual exam.

The "Squid Game" study group, which has been operating consistently from the 3rd to the 11th session,
is a proven learning community with over 1,500 cumulative participants and a large number of successful candidates to date.

From rounds 3 to 10, it was a brutal survival-style study group where you were 'removed' if you failed to complete missions,
but starting from round 11, it has returned as a new completion-based challenge with no eliminations. 💪🔥

With a focus on consistency and immersion,
let's build a real "passing routine" together, moving forward one step every day.

1. Check the Mission

Check the missions provided daily. Review the missions offered in the books or lectures, and either follow along exactly (Kkakdugi) or write the code yourself (Challenge). The mission submission deadline is the same day + 1 day.

Mission Example


2. Submitting the Mission (Must use the code block feature!)

Please write your solved code! There are multiple mission problems. When submitting, you must select the 'Code Block' function to enter your code. Clicking the code block icon will display the Python code neatly.

How to write code


3. Communicating on Discord

🙋 Learner

  • On Discord, we freely exchange opinions regarding the daily missions and share each other's code.


🧑🏻‍🏫 Ddan짓 After Work

  • I provide public feedback on content worth sharing from the missions or on incorrect information found during Q&A sessions between learners.

⚠️ Precautions when writing questions

  • Please make sure to follow the question writing rules :)

    I'm an "I" type who usually doesn't do study groups and worries a lot about what others think. I was going to prepare for this course on my own, but I joined because I needed some motivation, and I highly recommend it. There's absolutely no pressure like that; you just submit daily assignments without being pushed, so you can go at your own pace. The live lectures also have so many great tips, which is a huge help! Thank you, teacher.

      I am currently taking the main practical exam course. I was curious about the current exam trends through a live session, and after listening to just the orientation, I feel like I've already gotten more than my money's worth. Also, the questions many others asked were things I was curious about too, so it was very helpful. I really appreciate how you clearly explained how to prioritize my studies for the remaining time until the exam. I will make sure to participate in the missions, even if I'm just a tag-along! Thank you.

          I had fun completing the daily missions. When studying alone, it can be difficult to manage the workload, but since the daily amount was set appropriately, I was able to study consistently without feeling overwhelmed. Thanks to that, I think I was able to build my skills by reviewing calmly without rushing. Thank you so much. ^^
