I don't usually leave reviews, but I wanted to recommend this one. I failed the first time I studied on my own, and I wanted to pass the second time, so I searched for success stories on Naver Blog and took the recommended class. In the end, I got 40 points on the 9th session's practical test 2 and 30 points on practical test 3, for a total of 70 points and passed! This time, practical test 1 was too difficult and I only managed to solve one, but it was wrong. However, I was able to pass just by learning practical test 2 and 3. And the biggest advantage of this class was the almost real-time Q&A. Whenever I had a question, I asked it and got an answer right away, so I was able to resolve it without delay. Some people say that it's a difficult class for people with no foundation, but I thought it was an efficient class without any unnecessary content, just for passing the practical test. I think it's a great class for people who have basic data knowledge and are short on time. Anyway, I passed thanks to you. Thank you!
