Hello! Thank you for your good evaluation and comments. Are you preparing for the 35th exam? The 34th exam restoration problem solution will be uploaded around mid-October. Please check it then and be sure to watch the problem solution video or solve the problem yourself. Also, if you plan to continue studying data analysis in the future, the ADsP content may not be enough. If you are interested, I recommend the Big Quarter Challenge. I registered first at www.eduatoz.kr, and you can apply for free lectures until the end of September. If you are interested, please contact imbgirl@naver.com. Thank you. Yoon So-young
