I've put about 2-4 hours a week into the ML class. However, I know that math (basic linear algebra and calculus so far) and have done scientific computing before so I can churn the exercises out pretty quick. The exercises are the best part. It's nice having a set of problems to work on instead of just watching an hours worth of videos each week.
