I chose the wild type recommended by the teacher and completed the course! As expected, the content was difficult because I didn't know, but I think I followed along with it with interest. When I saw the lecture where the part that was missing was red when signing up for membership, I thought to myself, "Wow! That's it!" Now, I will go back to the basics and study while chewing over the content I learned here. Of course, I am also reviewing. I will work hard, teacher!
