Whether you are a major or not, I think this is a must-have lecture to save your time. Because it fits the reason why the lecture was created. (Purpose of the lecture: To shorten the preparation time and provide an efficient preparation process for students to obtain a job in data science by providing organized information on the parts that the instructor was confused about while preparing for data science.) Personally, in the last stage, I think it would be better if the instructor shared the links that he recommends or is already subscribed to, although each student has a different desired career in relation to specialized books and newsletters/blogs. Thank you for the great lecture.. I listened to it all at once today and haven't been able to answer all the practice problems yet, but I don't think I will study anxiously without a clear roadmap. Thank you again for providing a great lecture!! ㅎㅎ If I have questions while sailing.. I will ask..ㅎㅎ Thank you!!
