I passed the 8th Big Data Analysis Engineer Practical Exam. Thank you very much. (60 points = Type 1: 20 points / Type 2: 40 points) I was a non-major + working person, and I didn't really study for even a week. I registered for the course a month ago, but I didn't watch half of the lectures until a week before the exam. From D-2, I only listened to the necessary lectures and practiced with the goal of getting exactly 60 points. I watched the lectures on past exam questions until dawn on the day of the exam, and followed along, aiming for exactly 60 points. The problem I solved with what I studied was 50 points, and I used the Big Data Engineer Exam Tips (dir and help lectures) to solve one additional problem and get 10 points, and I passed. I don't recommend cramming, but if you have about a month to spare and follow the curriculum well, I think you will easily pass with a score of more than 60 points. Thank you for the great lecture.
