The lecture videos are great because they are compact and focus on the core essentials. In particular, the content explained in theory matches the actual code almost perfectly, making it very easy to understand. Thank you.

I took this course to prepare for coding tests. The instructor explains the theory in an easy-to-understand way by simulating the process of applying algorithms to problems step-by-step. After the explanations, I was able to gain a solid understanding by solving examples where each algorithm could be applied. Additionally, the practical tips shared throughout the lectures for solving problems were all incredibly helpful. As a result, I have developed the ability to solve many more problems than when I was studying on my own. If you feel stuck while preparing for coding tests, I highly recommend taking this course! Thank you!!

It was time to prepare for coding tests, but I felt overwhelmed and didn't know where to start. This lecture was a huge help in establishing a guideline, as it began by identifying exactly which concepts are necessary—the very starting point I was struggling with—and explained the roadmap for moving forward. Of course, it didn't just set the direction; I also appreciated how it covered how to study and the reasoning behind the choices one must make before solving a problem. Thank you for the great lecture. I will continue to study hard.

The instructor first explains the concepts necessary for coding tests and provides clear explanations on how to approach problems using those concepts. In particular, I liked that they don't just teach problem-solving techniques, but clearly point out the reasons and criteria for choosing a specific algorithm after reading a problem. I was feeling lost about how to study for coding tests, but thanks to this course, I feel like I have a much better grasp of how to approach the problems. I highly recommend this lecture to anyone who, like me, is struggling to find direction on how to prepare for coding tests.

It was truly helpful because you didn't just explain the concepts, but pointed out the reasoning behind why we should think that way. Explaining the structure with drawings helped me understand the abstract algorithms much better. Instead of jumping straight into writing code for the problems, you showed the flow of thought first, which made me feel like I was learning the actual approach. In particular, simulating the difficult parts yourself was a huge help in getting a feel for it.
