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.

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.
