I've started to tread a more serious line on the AWS associates exam. I'm angling for the solutions architect, but the toughest exam at this level is supposedly the SysOps Admin, which I did last year.

I ended up dabbling in a bunch of the simple and short lessons already, and now I'm just about half way through one of the prep courses for the exam. I think I'm going to snag another course to augment the one I'm doing, plus after I officially get half way I'm going to start doing the practice exams I bought a few months back. In the next little while, I'm also going to grab some courses for the professional exam, so I can get that ball rolling.
