Hello, this is Reve :) First of all, thank you for taking the course and providing your feedback. Regarding the hands-on exercises, I wanted to focus more on the core essence of the lecture, and I believed it would be more helpful for students to understand and try things out for themselves while going through their own trial and error. If it becomes necessary in the future, I will consider reviewing the practice sections through Inflearn Live or additional recordings. Thank you. Best regards, Reve.
