Professor Ying has been an amazing professor this quarter. Her lectures have been engaging, extremely organized, and overall made the course much more interesting. Lectures match slides, so if you cannot attend lecture, you will be fine. Section attendance is mandatory, however. There are chapter quizzes that are about 1-2 per week, but she uses a system that is tied to the textbook, so you do need the textbook. These "quizzes", called InQuizitive, must be completed before the deadline but you can work on it until you get 100% and your progress is saved (they're super easy). She also has two short papers (two pages max.) and one exam (final). Overall, I highly recommend this course and Professor Ying!
