This is the best coding test lecture I've seen so far. It was great because it reduced the scope of coding test preparation to what companies require and provided code examples that contained the thought process, were concise, and optimized for practical experience. What was best was that they shared knowledge gained through experience about how to approach these problems, which problems to choose, and that what isn't working now is just part of the ongoing learning process where things don't work, don't work, and then eventually do work. It was truly, truly excellent. As a major, it was like seeing content I'd already seen, so disbelief in myself and the lecture occasionally arose during the course, but each time, I was captivated by Heybob's excellent teaching skills, the fact that it was divided into short segments making it easier to listen to than long lectures, and the practical know-how. I consistently progressed a little bit every day without missing any, and it seems like a big gain that I've become much more confident than before and no longer fear solving coding test problems. Thank you once again for creating such a good lecture. If you have a weakness in coding tests and are hesitating to enroll because of the price, I, who completed 100% of the course, guarantee you should never hesitate.
