Thanks LinuxAcademy for the training. From 0 cloud knowledge to a good first step. The Orion Papers is a great way to teach. For a sys admin, this is the best way to enter cloud services.
As for the exam, invest in doing a lot of questions. Questions train your mind for the AWS format, and make you do the labs & listen to videos for details you might have skimmed the first time.
There will be times when you are demotivated. (like I was). Make LinkedIn your homepage. Follow Anthony James & Linux Academy. The never ending stream of people getting certified daily will give you the kick you need to get back on track. Also, those Linux Academy YouTube Videos on Student Success... great help to center your focus.
Definitely doing more certs, with Linux Academy for training.
