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

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..!

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.

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