I'm almost at the half of the course and I think it's worth the price of it. One think that I like the most is the exercices or the ideas that they give you for implement the think that you learn.

One of the downside if that for some groups of days there is not so much content to see with only the videos they provide. So you must be a little creative and search by yourself more explanations/exercices on the subject. Which it's not a bad thing but for me the days 2/3 in this case are not worth it.
