Not impressed. Whilst I have worked with computers including building & repairing for years, i thought it would be useful to learn some basic skills surrounding coding for OS'es. I looked at C & lesson 1 is just pretty much a click, lesson 2, I have not a clue what they are talking about! Starts taking you into print commands with headers, files etc. Has literally no instructions on what to do, how to run the script or if that is even what you are supposed to do.
