I often find a lot of free stuff, whether it be a time limited trial or simply free, never quite matches the expectations.
The Shaw Academy Blogging and Graphic Design Midule 1 Diploma courses really do change my opinion. They are really rather good.
In both I have learnt multiple pieces of information that I will be using, as well as validated things I was taught 30-odd years ago.
I am currently 25% through the Graphic Design course and waiting for the 4th session on the Blogging course. I am suprised by how much I am looking forward to both, in the knowledge that I will takeaway more, I will grow a little bit in each session, and I may yet use what I learn to develop my on-line presence in many areas.
