Unsure about tech class relevance

[Dimetime35c]

Okay Im currently taking an A+ hardware support class to get the basics for the comptia test. The book we have is covering thinges that I really feel are so outdated that it really isn't needed to know it. For cpus it's most recent intel covered is the 3rd Gen Sandy bridge. Yes I know the average user doesn't have gaming rigs. But how relevant is learning things about ivy and Sandy bridge and older ones when the current generation is at haswell and skylake? I mean it's still talking about agp slots on a mb. Do they even make mbs with those anymore? I'm just worried I wasted my money on the class and I'm starting to really struggle to force myself to go to class mainly due to lack of interest in learning outdated tech.
