I really hate the phrase, "Memorize~ Memorize~~" in all of this instructor's lectures. However, I paid the money and started listening because I wanted to save money. What this instructor meant by memorize was that it was important, so I had to memorize it. I thought the rating was fake after seeing the rating, but when he started explaining his charm from the beginning, my doubts disappeared and I ended up watching the whole lecture. I bought most of this instructor's lectures during the sale period, so I haven't watched them yet, but I acknowledge the outline. I recommend it.
