My current status is that I have learned Java and only learned Python grammar from a book for the coding test. I have recently taken the coding test a few times, so I have not listened to all the lectures, but I have listened to half of them, and I am leaving a review after repeating them 2-3 times. Advantages 1. I learned that I can solve the coding test this way (thought) I had never thought of solving it with an exhaustive search before, but now that I know that I can solve it this way, I am able to solve it better. 2. I can solve some bronze problems and some silver problems. Before, I could only solve problems that I knew the real grammar, but now that I have solved some silver problems, I feel like I have grown a little. 3. If you understand it, you will gain powerful tools. If you understand it 100%, you will gain a strong weapon to deal with the enemy called the coding test. Disadvantages 1. You may have to repeat it more than 3 times to understand it. (This is my subjective standard.) I forgot which lecture it was, but after watching it more than 3-4 times, I was able to understand that part. (But there are times when I forget againㅋㅋㅋㅋ) 2. It can be difficult for beginners. It was difficult to understand from my perspective. (Coding Sensei said it was easy, but from my perspective, there were many times when I didn't understand it..ㅠㅠㅠ I don't mean to criticize.) I think it would be good to solve Python grammar + 100 basic Python problems before listening to this. I'm sure that it wouldn't be a loss to buy it at this price and this level of quality.
