1. I often wasted a lot of time watching videos and following the code, but since the lecture materials were provided separately so that I could copy and paste them, it was good that the videos explained how the code worked, making it easy to understand. 2. The tempo felt fast. I skipped over the parts I knew right away and went back and listened to the parts I didn't know or didn't understand well. 3. I had studied React to some extent, so it was easy to follow, but if you're not familiar with JavaScript, it might be hard to follow. 4. Since it's a full-stack course, it doesn't go into detail, but it was enough to complete the project. 5. I felt like it was more expensive than other lectures, but I think it was worth it because I got the basic code for working on an AI project and it's a topic that you can't find in other lectures.
