I ran across Professor Messer's videos on youtube and had to check out his site. His videos are incredibly simple to follow and he doesn't bog them down with a lot of extra nonsense.
If you want to study for the A+ exam or just want to get involved in a great IT community - check it out.
There is a lot of free content - but paid content is also available on some of the beefier IT subjects.
I considered putting 4 stars here just because I haven't personally purchased anything from the site - but I simply can't find a reason to. Professor Messer seems like a very nice guy who just wants to help educate the community and why shouldn't he offer paid lessons?
