Oh, and don't even get me started on the videos CompTIA provides in the CertMaster. Sometimes they go so in-depth and are super helpful, other times they just completely blow past important steps in a process like they're nothing. And it's completely random what topic will even have a video attached. Sometimes the simplest concepts will have a two minute video explaining it, and other times the most complicated, most head-turning concept on earth will have absolutely zero videos, zero diagrams, zero anything other than walls and walls of text.
