I have been enrolled in 3 courses for a long time, but due to circumstances not progressing fast, I do all at same time and have done 2 modules of each so far focussing on each module on specific days. I prefer to have material available offline, which this course sadly doesnt approve. So I copy paste my own documents. That being said, I love the courses and the content, its absolutely not lack of interest that lags me. But Im not much a theoretical learner, Im more hands on and visual learner, thats why I like off line material so I can make markings, drawings etc to it easier.
