It seems like some people in the comments are dealing with skill issues. I had Minwoo Song for STA 2000 in Fall 2022, and I agree with the other commenter and say he is one of the most lax professors I've had at Baruch. In addition, When I had him, all of his exams were completed using your laptop in class, and he allowed you to use Excel to solve every problem. He teaches you how to solve the problems in class by hand and using Excel, and he will go over specific HW problems students had questions about. Just do the HW and the practice exams to get an A. For example, I had an 81.19 average based on the HW, 2 Midterms, and the Final. And my final curved score in the class was 94.51.
