The questions were a bit easy, but I still liked it because it felt like I was building up the basics! If you also do a special(?) for preparing for coding tests, I want to take the class right away~~

[A hundred words are not as good as seeing once] Intermediate SQL problem solving for data analysis

Baby Pig, this is a special lecture on preparing for coding tests! The idea is good. I should think about it seriously. Haha. It is the most encouraging word to the person who creates the lecture that you are taking the lecture right away even if another lecture is released. Thank you for your review.
