[2025 Latest Exam Questions Reflected] Big Data Analytics Engineer Practical Exam 100% Pass! The Pattern of Past Exam Questions Becomes Clear!

Concise and good. Thanks to it, I passed the 10th exam!

No help from other courses, I passed 1st try with 90, only with this course.🖐 Excellent course for learning from basics to application. Thank you!!!

I think it's a compact lecture for preparing to pass the certification exam.

Today was the preliminary score announcement day, and I passed! I couldn't solve Type 3 at all due to insufficient study, and in Type 1 preprocessing, I only solved 2 problems, so I had to get a perfect score in Type 2, and fortunately I did, so I barely passed with 60 points. The advantage of this lecture is that it proceeds with learning based on actual past exam questions, making it easy to adapt to exam problems, and since the lectures aren't long, efficient learning is possible. The instructor also conducts the lectures smoothly without any hiccups, and especially answered questions very quickly. I also think it's a big advantage that the lectures aren't boring. However, regarding the encoding or scaling process of Type 2, I hope additional explanations (which encoding to apply in which situation, which scaler to apply to perform scaling, etc.) are added a little more. It felt a bit like I was just memorizing code..😊😊 Of course, even if you just memorize the code template, you can get a perfect score in Type 2. For this exam's Type 2 problem-solving, I used the 'one-hot encoding + RandomForestRegressor(Random_State set to 42 only)' template and got a perfect score! I didn't even do separate scaling. 코딩 대한민국's YouTube Preprocessing 100 Problems and this Inflearn paid lecture were really a great help. Thank you. * Since I barely passed and left a course review, for those who might be looking for 빅분기 practical lectures, I'm leaving an additional comment in case it influences your choice of lecture. I only barely passed because my study time was too short..😭😭 I'm also a beginner non-major😊😊 (Passed written exam on 2nd try, practical on 1st try!)

Best teacher, best class

It was so incredibly helpful. While working, finding past questions or mock exams was a struggle, and I was at a loss as to what to do, but they provided all the code and explained everything kindly, thanks to which I passed! ! It's the best!! Highly recommended!!

For those with Python experience, I think it's a straightforwardly good subject.

It was really helpful in preparing for the Big Data Analysis Engineer practical exam. Thank you.
