1. Pros The textbook and source are provided, so it's easy to review. (This is why I signed up for this course.) 2. Cons The lecture has some parts like reading the textbook, so the delivery is poor. When explaining the code, there are many cases where the code is simply read while typing. (Unfocused, time wasted when reviewing) 3. Suggestions I would like you to reduce the time for simply typing the code and reading the code, and increase the time for explaining the source. Drawo io is inconvenient to read, and I can't access it at work due to security reasons.
