Hello, Knowledge Sharer. I registered for a class somewhere else about two weeks ago and then received a text message to take an online class. First of all, I would like to express my deep gratitude for the wonderful lectures that gave me a few days of happy learning. I think it would be good to quickly review the overall content and then practice step by step, so I listened to the whole thing once I understood it quickly and skipped over it once. Now I will try to master it by repeating it from the beginning several times. I especially want to try implementing my own strategy that you mentioned. That is exactly why I started studying. What I thought was so great about the lecture itself was that it explained the questions that came to mind right after learning something. Also, thanks to the explanation of the basic principles in the beginning, it was much easier to understand the actual examples in the latter part. I can't wait for the next lectures. I will diligently review what I learned and study the lectures that are currently uploaded. I regret that I cannot express my gratitude in words. Thank you so much!
