As a non-CS major, I've never systematically studied algorithms, so I always felt scared and wanted to avoid coding tests. I bought and took several coding test courses, but most of them felt like watching someone who's already good at it solve problems effortlessly, which often left me confused as a learner. Then last year, I took the Coding Test All-in-One course on Inflearn, and it really helped me build a foundation with visual explanations starting from algorithm basics and showing how to approach problems. That's why I signed up for Killing Camp. Killing Camp has quite challenging problems and requires solving many problems each week, so I think it's worth the money for those who have basic concepts down and can dedicate enough time! This time, I participated for 2 months with the goal of solving all the assigned problems each week, spending at least 2-3 hours daily, sometimes 5-6 hours. Each week focuses on a specific algorithm topic, so I could learn patterns by reviewing concepts and then solving related problems consecutively. It's not easy to consistently study for coding tests alone, but in Killing Camp, having others studying together during the set period really motivated me as we shared our progress, and I was able to participate until the end. I recommend this to those who are always held back by coding tests, feel lost about how to approach problems, and want to properly invest time to thoroughly prepare for coding tests!
