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.

I don't feel like this was adequate at all really. It was a ton of jargon blasted off at a thousand words per minute. I watched all the videos several times, and the questions and quizzes seemed very disconnected and obscure in relation the actual course material. Half the time things that were right answers were wrong, questions worded poorly, and a lot of vague stuff.

I'm a huge note taker, and I didn't even know what to take notes on or what is supposed to be important information. Half the stuff was never touched on again, and the other half of stuff was touched on all too briefly.

Do I have more knowledge than I did before taking this course? Yes, a bit. However I feel most of what was "taught" (or being spoken at you) in this "course" was very fleeting and ephemeral information.
