I knew nothing about coding tests, but I feel like I was able to quickly build a solid foundation. Thank you!

The code visualization part was a huge help in understanding data structures and algorithms. It was a great opportunity to gain a detailed understanding of time complexity, and I'm glad I chose this course for my first time learning data structures and algorithms. I am very satisfied and highly recommend it to beginners.

The course content is good, but errors occur far too often on the coding test practice site... 😨

I've completed the entire course. The visual effects and detailed explanations of algorithms I only vaguely understood were extremely helpful for my comprehension. Since the lectures were edited to be compact, I was able to repeatedly watch the difficult parts without feeling time pressure, which was very helpful. I've never left a course review before, but I think this will be a great help for coding tests.

I understand so well!
