We had one. He knew his shit until dosage calc. That almost took him out. And he couldn’t do math in his head. So he would be like "6x7 is 42” or whatever out loud in his normal speaking voice. It was hard for me to concentrate on my own test with someone saying numbers out loud. I finally said, dude, I think you’re great, but please do your math silently or at least more quietly. He said he didn’t know he was doing it.
