I rushed over here because I heard Mr. Noh published the "Coding Test Bible"🥳. Last year, I took the Coding Test All-In-One course and conquered data structure and algorithm concepts and representative problems that I found difficult. Through the Killing Camp, I systematically repeated problem-solving and grew a lot. In the process, Mr. Noh's lectures were, of course, a great help, and the Python materials for coding tests provided by the Killing Camp were very helpful in solving problems! And it seems that this "Coding Test Bible" is a final version that compiles those materials, concept explanations, and templates into one place for easy viewing. Personally, I highly recommend watching it with the Coding Test All-In-One course, which I loved so much, but this book also provides detailed explanations, so I recommend reading it carefully and repeatedly to make it your own! Participating in the Coding Test All-In-One course + Killing Camp last year was a major turning point in my career, and thanks to it, I overcame my fear of coding tests and successfully moved to a well-known tech company in the United States with a 3x salary increase😊😊. If you have the will and persistence to repeatedly learn the contents of the lectures/book and representative problems (templates), and then solve applied problems based on that, you will definitely feel your skills improve rapidly. Be sure to solve the problems you have solved repeatedly with a time gap. If you close your eyes and solve about 50 problems repeatedly until you memorize them, it will become really easy from then on. I'm a fan of Mr. Noh's lectures, so I got carried away writing a review out of fandom😊😊. In conclusion, I highly recommend repeatedly reading this book or taking the lectures to build a foundation, and if you have the time, participate in the Killing Camp! If you have the will, it will be a worthwhile investment🙌.
