Personally, I found this course more dense than the previous courses. I would have liked to have seen more visual descriptions of the topics, e.g. cryptography. But other than that, great course :)

I feel like this went way more in depth than I think most people just getting into it can handle. I think either this needs to be dumbed down or drawn out a bit more, but a lot of great info.
