I found out about it a while ago and i'm thinking about applying for a course.
You say you are learning a lot from it, would you reccomend them overall? Also, do the courses actually start on the dates given, or is that just when they become available, and you can do them at your own pace after that date? Is it really as good as it appears/are the courses really completely free?
Sorry for all the questions, i'm just curious. You don't have to answer them if you don't want to.
Hope you continue learning and enjoy yourself.
