Hello, Mina Lee. I see that you've left your first review for the course, and I'm sorry to hear that you're already finding it difficult at the 30% mark. However, this course is not a simple AI utilization class where you just input prompts into ChatGPT or Gemini to get results. It is a hands-on, practical course where you are expected to execute the content yourself, verify the results, and learn by troubleshooting any issues you encounter. Therefore, it is difficult to understand everything just by watching; the process of actually building and following along with the lectures is essential. For parts you cannot resolve, communicating with the AI or actively using the Q&A board will be very helpful for your learning. Thank you for taking the course.
