I passed my first practical exam on November 29th with a score of 85 points. I was able to pass by watching 퇴근후딴짓's videos and reading the book, solving the latest problems multiple times, and studying through the kind explanations and example problems based on code. I'm really grateful for providing such great materials that helped me pass on my first attempt.

As a non-major working professional, I studied hard and passed both the written and practical exams on my first try in the 11th session 😊😊 From a non-major's perspective, the content wasn't easy, so I studied the parts I didn't understand 2-3 times and repeatedly solved past exam questions~! The instructor explained difficult parts easily and gave helpful tips, which I think helped me pass! If you want to study the key points and pass quickly, I think you'll get good results by taking this course. Thank you~~

I passed the practical exam on my first attempt with a score of 65! I was worried about whether I could prepare properly in just 28 days, but the instructor provided simplified versions for each type tailored for short-term preparation, so I studied by reviewing each type and then going into more detail on Types 2 and 3. Since I'm a major student and had studied some basics of related content in college, I was able to handle it easily. For beginners, I recommend listening to the concept-focused lectures first and then getting familiar with the problems along with Kaggle! Type 2 might be a bit concerning since it's scored by section and there's a lot to memorize, but as you study, you'll find that Types 1 and 3 aren't as difficult as you might think! The content in the lectures alone was more than enough to learn the problem types and each case without any issues! Once again, I'm truly grateful to Toigeuhn-huddan-jit for providing such a helpful lecture, and I hope you all pass after taking this great course!

I passed the practical exam on my first try I gave myself a generous month and a half to prepare, and starting a month before the exam, I made an effort to practice for 1-2 hours every day while working on the Squid Game mission

I'm an office worker and I passed the 11th practical exam with a score of 85. I casually watched the lectures during my commute to familiarize myself with terms and concepts, and for the last 2 weeks, I practiced coding for about 2 hours after work each day to prepare. Personally, due to company security issues, I had restrictions on my practice environment and couldn't use cloud-based Colab, so I prepared for the practice from the beginning in the exam environment, which I think actually helped. I wish everyone success in obtaining their certification!
