Since my undergraduate days, I've always struggled with data structures and algorithms classes. Even after graduation, I kept failing interviews because I didn't properly prepare for coding tests. I tried various courses and books, and mindlessly solved problems. After much deliberation, I applied for and completed the 9th cohort of Killing Camp. Although the process of solving, analyzing, and learning from problems each time was difficult and overwhelming, I regretted not taking Killing Camp sooner. I believe that with well-prepared materials and systems, what you gain depends on how much effort you put in yourself. The abundant and diverse materials helped me understand well, and it's reassuring that questions are answered with quick feedback. Through Gaebalnamnoh's live lectures every Monday, I could communicate and being with other passionate students in real-time was very motivating. The daily evening study sessions were also a great help. Please make sure to participate in the daily study sessions. Even when you don't feel like it, you'll find yourself naturally doing it when you're together with other students. You won't understand everything from the start. However, it depends on how much time you invest and how much you review. Even after completing this course, you need to keep reviewing and studying. Instead of fear of coding tests, I gained confidence that "if I do this consistently every day, I can pass coding tests too." If anyone has similar concerns as mine, I recommend challenging yourself with the mindset of "let's go crazy about algorithms and coding tests" for the nearly 2-month period!!
