I am a non-major who only knew Python grammar. I didn't even listen to Type 1, but the day before the exam was approaching, so I listened to everything on the same day without coding. Thanks to the instructor's teaching skills and content, I was able to pass by getting both Type 1 and 2 right. I definitely got 0 points by watching the lecture at 2x speed without coding Type 3. The exam is over, but I am listening to Type 3 here and there. Of course, I don't recommend cramming, but I wanted to tell you that if you have this lecture, you can pass the exam if you do. (This time was a bit easy. If possible, don't cram..) I was too lazy to practice, but I am confident that if you take the class systematically, get feedback from the instructor, and build up your knowledge, you can pass regardless of the difficulty level. Thank you for providing such a great lecture!
