Thank you, Teacher, I got a perfect score thanks to you! I studied diligently, listening to lectures for 1 to 3 hours a day over 3 weeks. I think your lectures were systematically well-organized, allowing me to solve everything without issues! Type 1 questions were all covered in the pandas lecture explanations, so if I had practiced the functions enough, I could have solved them easily! For Type 2, I only had time to study preprocessing, random forest models, and evaluation metrics, but fortunately, I think I got everything right on the exam without major deductions. There was an issue with handling missing values as 0 this time, but I submitted it with random forest without processing them and got a perfect score! For Type 3, when I submitted with sumarry(), I got everything right without any problems. Being able to solve all the problems within the lecture content was very helpful. I wanted to solve all the Kaggle problems from the study group, but I couldn't due to lack of time. Nevertheless, having various practice problems, solutions, and Tip within the lectures seemed to be sufficiently helpful for understanding. I was worried because there were quite a few stories about it being difficult for non-majors, but I feel confident that if I trust and listen to your lectures, I will definitely pass! You're also conducting various other lectures, and if I get the chance, I'd definitely like to take them. Thank you, Teacher!
