23 PDU "Project Management Basics" course - complete waste of my time?

Hi all. I am prepping for the CAPM exam and have been working my way through the online PMI-offered, "Project Management Basics" course. So far, I feel like it is a massive waste of time. The subsections are so incredibly granular that I find myself losing focus as to what the chapter is even covering. The "take a quiz before you start a module" thing seems like a waste. I don't know, just feeling SUPER burnt out and have lost momentum. Do I keep going? I am about 45% done and feel like I've been working through it forever, taking diligent notes for each subsection. Any suggestions are greatly appreciated.
