Finally finished the regular course! I wanted to make an app, so I bought Howl's book 'Building Android SNS Apps with Firebase', but since it was my first time programming, I was at a loss. Then I found this course by Howl and paid for it right away. All I knew was a little bit about HTML and PHP, but after taking this course, I gained a concept of programming and was able to follow Howl's course on YouTube on how to build SNS apps. I think each course is well-made so that I can learn intuitively. Thank you. Please continue to give great lectures!!
