I've been wanting to learn Linux for about 2-3 years, now, and I've always found excuses not to do it myself. Work has offered two 1-week classes (Beginner and Advanced), so I've jumped on it.
I do have a "Beginner's Guide" that I found for free on Kindle, but I haven't read it yet. Is it worth working ahead of the class, or is it better to just let things progress? For perspective, I was able to set up RetroPie on a RaspPi a few years ago thanks to a video guide, but that's as far as I've been into Linux. I also have no idea what flavor of Linux we're going to learn.
So, any high level tips or other suggestions? Do I need to take really thorough notes?
