Take a Linux Course

Need to take more in-depth Linux course: like how to install Linux, how to solve problems encountered during work, console commands. searching for files, setting up network, and so on.
I use linux for around 10 years now or even more, but still at the level of a simple user. There's no hope that I will learn something at the University, since the learning process is at its lowest level, below anyone's imagination.

I'll do the studying in my spare time, I think like 7-8 hours per week or so.
