I passed the practical exam on my 11th attempt in one go. I'm a late-starting office worker from a completely different field, but I think I was able to pass thanks to the excellent lectures. The instructor explained things repeatedly in an easy-to-understand way, continuously updated with new content, and it was really a huge help for me who was doing other things after work. Not only the lecture content but also guidance on exam preparation... I could feel the instructor's passion and affection for practical exam candidates. I sincerely thank you and strongly recommend this to those preparing for the Big Data Analytics certification. If you prepare with the instructor who does other things after work, you can pass!

I had no foundation in Python at all and felt lost after passing the written exam, but I passed with a high score of 90 points thanks to this course and the Sinagong book. The instructor explained everything systematically from the basics, and the coding was more stable and structured than other courses, making it easy to understand. There was a lot of controversy about the grading of Type 2 questions in the 11th exam, but I systematically coded line by line using the method the instructor explained and got a perfect 40 points without any issues. I was anxious because I had nothing but this course—no other practice problems or information—but fortunately, the exam didn't deviate much from the Sinagong book and the course. The Q&A responses are quick, and because the course makes things so easy, you might start to doubt the instructor's approach as you study, but just trust and follow the instructor and you'll definitely pass. I passed thanks to the instructor. Thank you so much.

Thanks to you, I passed the 11th practical exam on my first try As a non-major who had never touched Python before, I listened to the lectures, practiced in the practice environment as instructed, and gradually became more comfortable solving problems through repeated learning. It seems like you've created the curriculum well enough that I could pass with just the lecture content alone, without needing any additional study. While I didn't get a perfect score, I passed with 30/40/20 for a total of 90 points, feeling like I got everything right except for the completely new questions. Type 1 For the 11th exam, Type 1 seemed to come out easy I repeatedly practiced mainly with past exam questions and additionally memorized the necessary code from the practice problems at the end of the lecture, improving my problem-solving sense through repeated learning Type 2 When I first listened to the lectures, it felt like you were teaching various codes in a somewhat complex way, but it's good to approach it with the mindset of following along first and then repeating after completing one full round of the lectures The recent past exam questions felt like they were organized to show only the essential code needed, so after learning it the hard way at first, by the end, the code was organized to the point where I thought "this much code is enough to get 40 points" and I memorized exactly that much until the exam Type 3 I personally think this is the most troublesome type if they make it difficult, but in this exam, there were about 10 points worth of questions I didn't know. Fortunately, if you just repeat the past exams, as long as the examiner doesn't create Type 3 questions in a different way from existing past exams, getting the questions you can answer right shouldn't affect passing I've explained at length above, but ultimately, one full round of lectures + repeating past exams + repeating practice problems at the end of the lectures I felt this was a well-structured course that allows you to pass by studying exactly this way I recommend it to those whose goal is to pass the exam quickly and reliably

I passed the Big Data Analytics Engineer certification exam (11th session) on my first attempt. Despite being a non-major, I achieved a high score of 95 points (30/40/25) thanks to the After Work Side Quest lectures! I'm truly grateful. My study method was: <1 complete round of After Work Side Quest lectures + repeated practice with provided practice/past exam questions + repeated practice with provided Kaggle problems + completion of all Squid Game missions> I recommend the After Work Side Quest lectures to these people! - Those who tried self-studying but feel anxious because preparation seems insufficient - Those with perfectionist tendencies who think "I need to aim for 100 points to comfortably pass 60 points" rather than "let's just barely scrape by with 60 points" - Those with very little time left before the exam who want to aim for a short-term pass somehow - Those who have no idea how to even start with Work Type 3 I originally planned to self-study for the practical exam, bought textbooks from other companies, and gathered various problems from the internet to solve on my own, but no matter how much I studied, I felt uneasy. I felt like I was missing something and wasn't sure if I was studying properly. So after much consideration, I decided to take the After Work Side Quest lectures. At first, I was suspicious it might be promotional content (sorry😭😭😊😊), but after completing the entire lecture once, I felt like I had a clear grasp of the overall exam. And the Kaggle problems provided through links were really helpful too. Especially for Work Type 3, which felt so overwhelming to prepare for alone, but after studying according to the guidelines presented by After Work Side Quest, I gained some confidence. I liked the lectures so much that I even participated in the Squid Game later on, and after completing the final mission as a challenger without being a reserve member, I achieved the excellent result of 95 points. I don't think I would have passed without After Work Side Quest. Thank you so much for creating such great lectures.

Hello. After passing the written exam on my 10th attempt, I scored 55 points on the 10th practical exam and 60 points on the 11th practical exam, finally passing, so I'm leaving this review to express my gratitude. For the 10th attempt, I could have passed easily, but I failed because I didn't check the significance level when creating the problem. I prepared for the 11th practical exam again, and at that time, I aimed for 90 points, but I'm embarrassed that I barely passed. However, without the lectures from After-Work Side Projects, I don't think I would have even passed by the skin of my teeth. Thank you so much. Have a great day. Thank you.
