Ya know what.. I tried and failed, many years in a row, AFTER I paid for the background check when that program first started. I can't pass it, I'm not trying to either. At this point, even if I could pass the test, I'm no longer physically able to do that much standing, walking and bending. And when I was forced to retire far too early, I was making four times as much money in 8 hours, and I was never able to reconcile that fact in my head.
I've said often on this forum, if you can't pass the certification, you probably shouldn't be doing the shop.
