I am currently taking the class!! But I am leaving a review because the class is so good! I will write down some of the good points! 1. Clean code writing method Usually, even after I coded something, I didn't know where it was wrong. I think I have improved a lot in that area!! It was so happy to be able to write clean code and code that I can read easily. 2. Practice problems, repetitive problems I have learned a lot through the above process of coding and practicing. I haven't seen many problems yet, but I think it will be more helpful in the future! I will leave additional advantages as I watch the class!! I highly recommend it to everyone preparing for the coding test!!
