So I just signed up, and I see that this is implemented as a track, meaning there are several edX courses required to complete it. Among those are Python for Data Science, Math for Artificial Intelligence, legal stuff, NLP etc.

I like how comprehensive this is. The problem (as I've stated before) with Ng's course is he hand waves a lot of the required math away which concerns me. Specifically vectorization I remember constantly being surprised what was possible mathematically instead of 'getting it'.

That said, is there an AWS version of this track? Maybe Math/Spark/Scala/ML oriented?

I do like that it seems comprehensive, so I think I'll invest time into doing it.
