The objective isn't to pass the exams it is to thoroughly understand the theory behind flying. I started the PPL aged 52 and spent a good 100 hours studying the Trevor Thom books alongside flying. I now have over 1000 hours and a full IR and I'm in my 60s. I still study to keep up to date and fly regularly mostly IFR.
I'm not keen to share the sky with folk who see the exams as a hurdle to be jumped before charging around the sky in blissful ignorance of half the basics.
That said, I haven't used a whizz wheel since I got my PPL and no longer even possess one
