I am enjoying the great lecture.

The lecture was well structured, focusing on content necessary for practical use.

A new type has come out, but nothing is uploaded, the screen is too big, but the code is too small, so it's uncomfortable even if the monitor is big... It's so disappointing...

It's a shame that I can't see the code unless I watch the lecture in full screen. It's inconvenient for people who don't have dual monitors..ㅠ I wish you could edit out the fact that it keeps going to other screens when looking at the Notion textbook..!

I'm not a major and I'm bad at coding, but I passed this exam with a perfect score on the performance test^^ I barely passed the written test so I didn't even think about the practical test, but the concise and efficient lectures were a great help. (The practical test was especially great...) I also appreciate the quick feedback on my questions. I hope you prosper always!!

Hello, Instructor Kim Dong-gyu. I am writing this because I got 91 points (21 in short answer, 30 in task type 1, 40 in task type 2) in the 4th Big Data Analysis Engineer practical exam through this lecture. I think it is definitely focused on the content for obtaining the Big Data Analysis Engineer. Saving the content I practiced with Colab and reading it through once or twice more for review was repetitive learning, and it was especially helpful to master my own optimized code based on the actual compression code. Instructor, I ask for many good lectures and I hope you prosper even more. Thank you.

It helped a lot!

I will work hard. Could you please give me your contact information?
