If you watch the lecture without any knowledge of jsp, it becomes typing practice. If it had been a little slower, it would have been a perfect lecture. The lecture is too fast, so I watch it by lowering the video speed to 0.75 or keep rewinding to see the code. In the lecture evaluation above, someone said it was like the instructor's review time, and I think it can feel that way. Still, thank you for making a great free lecture!
