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 :)

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.
