I totally agree with what other people said about the class review, saying that it was easy to focus on the class because the speaking speed wasn't fast. Basically, it's good to not be fast so that you can do things like 1.25x. When I look at job-related problems these days, there are more problems like "If you have a, find b" than intuitive problems like "What should I do about this?" If you learn it properly here, it seems like it'll be good for gaining confidence in how to solve coding test problems that may seem abstract. I personally watch it whenever I'm curious about other people's perspectives or feel lazy, and I wish I had seen this kind of lecture in the past! I'm watching it while thinking~~~~
