This thread is a good reference.
Back in the day when I first wrote my test, I knew the book front ways and backwards. I passed no problem.

Fastforward a few years and laws and procedures changed, and I would ask the new guys questions because they learned all the new stuff. Us old guys can learn from the newer guys.

FastForward a few more years and I had to get the handbook to study because of what I have forgot and what has changed.

Good to have this resource here.
