Hello. I passed the practical exam in "Non-major + First Exam". I was lucky to pass the written exam because it was mostly about memorization, but when I actually tried to prepare for the practical exam, I was at a loss. I thought that self-study would not work, so while looking for a lecture, I happened to come across Mr. After Work's lecture on YouTube, and I took the lecture through Infraon. What helped me while studying were: 1. Easy explanations that even someone like me who had never touched Python could understand 2. Curriculum structure just for the Big Data Analysis Engineer practical exam (the best) 3. Review using blank notes, Kaggle, etc. 4. Quick feedback on questions Etc. I studied while working, but just listening to the lecture and reviewing was a great help and not difficult. In the actual practical exam, I couldn't solve the 3rd type 2 question that I had never thought about at all, so I turned it in blank (15 points deducted), but I got everything else right and passed with a score of 85 (final result). I am so grateful that I was able to pass the exam and learn the charm of Python through Mr. Afterwork's lecture. Now, I want to continue learning not just by passing the exam, but to acquire more functions of Python that I don't know about and to utilize them more. I hope that it will be helpful to those who are considering taking the course, so I am leaving a review. I sincerely thank you for creating such a great lecture!!
