10-Week C++ Coding Test | Algorithm Coding Test
The conceptual lecture part is good. It practically explains only the important concepts needed for coding tests, highlighting them for real-world application. However, the problem-solving explanations are honestly very disappointing. I believe many students attend the lectures expecting to see the thought process of how to approach each problem and why that approach is taken. But most of them are simply explanations like, "This can be solved quickly like this." This is especially prominent in the dynamic programming (DP) section. It doesn't explain optimal substructure, nor does it provide a precise definition of the array used in DP (how it should be indexed, what the stored values mean). Especially, I know many people find it difficult to derive the optimal substructure, but the lecture doesn't explain this derivation thought process. It seems better to just skip the problem-solving sections and only do the selected problem solutions... But then, a strong question remains: why should one buy the lecture for such a high price?

It was very hard to study feeling lost and find ways to approach problems, but because you taught me the approach methods and even shared tips, I gained confidence that I would pass the 코테 if I just keep doing it this way consistently. Thank you so much for always replying sincerely even to very easy questions. :)

1. Top-notch lecture quality (After taking about 50% of the lectures, my perspective on problem-solving has truly shifted. I'm excited about how much stronger I'll become after watching all of them.) 2. Lecture materials and lectures are updated very actively. 3. Student questions are handled exceptionally well; it makes you wonder how they manage to answer so many. 4. Good voice. 5. The jokes sprinkled throughout are somewhat funny.

The lecture content itself was substantial and helpful. However, there was some discomfort in listening to the lecture. During the explanation, the pitch of the voice kept changing, and the rising intonation and expressions like "↗~doing it→" or "What!?" in the speech pattern were repeated, making it difficult to concentrate. Also, in the drawing explanation part, because it was drawn extemporaneously, the shapes were not standardized, and the handwriting was difficult to read, so the image or concept the instructor intended to convey did not come across clearly. Since the content is good, if the delivery method were a little more refined, it would be a much better lecture.
