Reading 24: interesting, but waste of time?

I just finished up FRA and although I found reading 24 quite interesting I am questioning whether it was a waste of time for the exam (much like visiting this site but I digress). I’m obviously joking with that ladder, but I was wondering if any of you had similar thoughts after reading the final section of FRA

joking about the ladder or latter?

why was it a waste of time?

Even i asked the same question here. But i did the eoq questions of that reading so you also atleast do them.
