Hello! Thank you for your review. It seems like the class was hard to follow. I speak a bit fast ㅠㅠ As you said, don't try to learn everything at once, but if you look at the big picture once and take the class again, I think you'll be able to learn it sufficiently. In the process, if there are parts you don't understand or don't know, please leave a question on the Q&A board and I'll help you. Thank you!
