I must say it's a really great course for those who want to study Marketing Analytics. The Prof introduces a lot of examples from specific companies like Airbnb, Snapple, Etch A Sketch.. to help students not only learn from theory in class, but also learn from real-life experience. There are also 2 peer-graded assignments which require grades from classmate, and I find this part interesting. Quizzes are neither easy nor hard, you need to work hard on the knowledge to be able to do math and choose the right answers. Overall, it's a really nice course and I really like it.
