Unlike a traditional "course", this one is delivered "on-line". The lecture is through videos, which are available 24/7. Take the course at your own pace, and interact with other students (and the instructors) through the forum. There are no late night calls, and you don't have to travel!
Each week, one or more lessons will be released. Each lesson contains the video materials to watch, homework and exercises for you to work on, and a quiz to assess your learning.
