Just light! Light! I am a true fan of the teacher..!! He is the one who made me realize again that studying development is this fun and exciting. After watching the introductory lecture on YouTube by chance, I paid for the roadmap without hesitation. These days, I want to see the next content quickly, so I am running after workㅠㅠ Usually, when I take other lectures, I have more questions like, "So why is it used?" "Where is it used?", etc., but The teacher's lecture seems to read my mind, and when I am curious, he explains it clearly! Thanks to him, I am studying without any obstacles. He explains it in detail, so I already understand 80-90% just by listening to the lecture. Even so, I am trying to chew on what I have learned and repeat it endlessly so that I don't get confused in the next level :) Actually, I was supposed to finish the basics by today and write a course review, but the polymorphism problem was too hard...sob sob.. I thought about it for a while and solved it, but I just turned it on to see the answer in the lecture, but as soon as I pressed play, the teacher said that I would gain a lot in the process of thinking about it and solving it, so I stopped again and am writing a course review while thinking about the polymorphism problem..sob hehe I will definitely solve it and move on to the intermediate level! Thank you so much for making life fun with such a great lecture!
