I passed~~ To leave a simple review,, I started studying with a goal of one month. When I looked up other people's passing reviews or study methods, it seemed like many people were taking Google Cloud lectures on Coursera.. But in the end, I think I made a good choice by choosing the only Google Cloud ACE lecture on Infraun! Coursera actually has a lot of lectures, so if you have enough time, it would be good to take them all, but I didn't have much time due to personal reasons. First of all, Code Banana's lecture was really good because it was structured so that you could also do practical training. And I think the lecture was structured around key concepts and services to fit the scope of the exam. I was a little disappointed because I lacked background knowledge on networks, but I think I just memorized it while solving problems.. ㅎㅎ I can speak Japanese, so I took the exam in Japanese, so at first, I solved only the Korean text problems twice each, and later I bought a Japanese workbook from the Udemy site and solved them twice each. Even the day before the exam, I got 40~60 points on the first set of problems I solved, and after organizing my wrong answers and answers, I got 70~80 points on the second set of problems. Still, there were quite a few problems from Code Banana's lecture that were on the actual exam~! I think I listened to the concept lecture again for the concepts or services that I was lacking here and there, but I somehow listened to the entire lecture twice. The lecture itself wasn't too long, so it wasn't burdensome to study while working. They say that the scope of the test overlaps with the professional-level PCA certification, so Code Banana, please make another lecture~ㅎㅎ
