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.

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 :)

This is the worst course I have taken on your website so far. A ton of information and different terms being thrown at me very quickly without going into any real detail. I feel I have learned nothing.

They don't give you the professional certification promised when you complete the courses. Don't bother. These courses will do nothing to advance your career or education.
