People I would recommend this course to: People preparing for the coding test I finally completed the course on July 14, 2023, when I bought the course and wrote a review, starting the semester in March 2023. I skipped 2 weeks each for the midterm and final exams during the semester, so I completed the course in 14 weeks. It's not 10 weeks, but it feels a little late because of school. I started with a blank sheet of algorithms, not even knowing if there was a site called Baekjoon or Programmers. I learned C++ because I'm an engineering major, but I've never seen it again for 3 years, including 2 years in the military + 1 year, so I started with almost a blank sheet of paper. I think I literally followed the instructions in the lecture. I studied the C++ textbook for about 2 weeks, went into the actual class, learned the concepts, solved problems, and if I got it wrong, I asked how to solve it, and when they answered, I followed them (they even always answered within a day). Before I knew it, I completed the course. Now I know what an algorithm is and can tell you how to solve a problem. I couldn't even solve Baekjoon Bronze problems, but now I happily solve Silver problems and I'm growing by getting 50-60% correct on Gold sub-problems. Of course, the problems included in this lecture are by no means easy. This is not an exaggeration..ㅠ When I took the class up to the 3rd week, I got almost all the problems wrong, so I doubted myself and wrote to the teacher, asking if I was really studying properly. Fortunately, I received feedback on this within a day, and I followed it. This is a lecture with really solid updates. There was a major reorganization during the period I was taking the class. The lecture was updated by incorporating the opinions of the students. I even confirmed that the questions I asked were included, which is a little embarrassing... But it's great that the code is clean... If you take this class, you will definitely have doubts dozens of times. Even though I looked at the C++ textbook, C++ is so difficult... How can I memorize it all? Every time I learn a new algorithm through a weekly lecture, how do I use it? How do I apply it? Should I just give up when I get a mistake on a problem that I sincerely solved and lose motivation? All of these answers are in this lecture. Each problem is mentioned dozens of times so that you can memorize it. You may still not know. You may still have questions. Then ask. You can get the answer to your question on the same day at the earliest, or within 3 days at the latest. Bigdolnim is the best! And fighting to all the other students!! **** Companies that passed the coding test as of January 17, 2024 Nexon, LG CNS, LG Electronics, Hyundai Motors, and other boot camps Although I did not pass due to insufficient specifications, I applied to companies that wanted to take the coding test and had good results at least in the coding test. I hope everyone will have good results through this lecture! Thank you. **I passed the final interview at LG Electronics!

Thanks to this lecture, I passed the LG Electronics exam!! I am a major, but this lecture is the first time I started studying for a coding test in earnest, and I would like to say that it was a great help. (They even praised me for doing well on the coding test during the interview ㅎㅎ) I highly recommend it!!👍👍

As IT becomes more crowded and competition for positions increases, the difficulty of coding tests is gradually increasing. I don't think that just doing 'implementation slightly, dfs/bfs slightly, dp slightly up to Baekjoon Silver-Gold lower level' like before can guarantee a stable pass. Personally, I think that maintaining consistency is important when preparing for a coding test. Even in the test room, I think that it is important to think about how to solve it according to the flow of my usual thoughts, and when solving the logic into code, rather than doing different implementations, variable names, etc. as I feel like, I think that I can avoid exceptions such as 'condition issues' by doing it the way I usually do. In that sense, I think this lecture is a lecture that I really recommend to majors. ES-> Time Complexity Calculation-> Finding Improved Algorithms that are the same for all problems It is based on a consistent solution for each week's algorithm, and you can continuously practice good habits that remind you that you have to pay attention to the consistency up to variable naming. ‘What kind of major would pay for a coding test?’ That’s right. You can do it on your own. But it’s a waste of time. I think that the carefully selected problems, consistent optimization solutions, quick query feedback that reduces the time spent on digging, and base codes through the textbook will be valuable leverages for majors as well.

    Pros ㆍ Quick answers to questions, quality communication and constant updates ㆍ Detailed explanations when teaching concepts every n weeks ㆍ Techniques for problem solving and efficient codes Cons ㆍ Lectures that feel like review ㆍ Lectures focused on algorithms (C++ basic concepts omitted) Personally, I think most of the cons are covered by the lecture materials.

    I finally understand why the lecture is only 8 weeks long but it takes 10 weeks to complete... The problems in week 8 are too hard ㅠㅠ But I can feel my skills improving as I solve each problem. I used to study algorithms on my own. However, I had no idea how to solve the gold problems. What really helped me with this lecture was that it explained the core problem-solving methods and useful tips for each chapter in an easy-to-understand way. It doesn't just teach short coding that is difficult to use in real life, but it teaches efficient coding methods, so I think it will be helpful when preparing for algorithm competitions or coding tests in the future. I also liked the selection of quality problems. I listened to the good lecture at a reasonable price. Thank you~

    I was often exposed to the C language in college, but I was worried that I wouldn't be able to solve the algorithm because I wasn't familiar with it. However, my worries disappeared after I solved the problems by looking at the textbook that only included the key usage methods. First of all, it's good that there are many fun parts in the middle of the concept lecture, so it doesn't get boring. I think the characteristic of Teacher Bigdol's lecture is that the explanation is not complicated and only tells the key points. However, in the end, I think the most important thing for coding tests is that you solve them consistently. I think that's also an advantage because you can solve high-quality problems that Teacher Bigdol has carefully selected.

    I've taken a few other coding test lectures, but there's no lecture as energetic as Bigdol's lecture. When I don't feel like studying, I feel energized when I watch the explanation lecture. I can see that you put a lot of effort into the algorithm textbook. When you first start learning algorithms in C++, you often don't know how much you should study, but this textbook contains all the content you need for algorithms, so it's good. I like that the lectures only explain the key points without long explanations. And they also select good problems, so I don't have to solve useless problems.!

    The explanation of the problem solution is very disappointing.
