I was able to pass thanks to you. Thank you. I am sharing my study method in hopes that it might be helpful to others. I listened to the lectures twice to organize the concepts and solve the problems. I also purchased the 'CS Roadmap 300 Questions' and focused on solving them starting two weeks before the exam. I went through the '3-Step Comparison Table' a total of three times. Since even a non-major like me passed, I believe anyone can pass this exam if they faithfully follow the instructor's lectures and consistently practice solving problems. After much consideration, I chose the CS Roadmap lectures, and in the end, I am very satisfied because the price was reasonable, the delivery was excellent, and I passed with a good score. The only thing I found slightly disappointing was the AI problem-solving section within the lectures; it would be great if that part could be improved.

I passed the 47th exam. The lectures are great to listen to while commuting on the subway. However, you probably can't pass by just watching these lectures alone; you'll likely need to purchase the textbook for in-depth study. The quizzes in the middle of the lectures are AI-generated and contained some strange questions, so I used Gemini to generate and solve about 500 mock questions instead. I studied for about three and a half weeks, and during the three days before the exam, I purchased the instructor's 300 mock questions and went through them twice, which I think helped quite a bit.

They teach very clearly and in an easy-to-understand way.

Good, I like it.

The diction is excellent, and I appreciate that you've explained everything in a way that hasn't been difficult to understand so far.
