First time I did integrad in 2015 we didn't need to know my 10 word for word.
In 2018 when I went a 2nd time (local class) I had to know every single word of my 5s and 10s plus know yard control/8keys/backing/5 keys slips & falls all word for word. Had to get at least a 94.9% to pass.
My wife helped with my 10s I would just keep saying them over and over with her stopping me when I messed up. We did it everywhere.... at dinner, at the mall, waiting in line at the grocery store. In 2 days I had it down cold
I reached out to a union head and they told me I need to know them word for word. Only have a few days left.
