“I’m the only president that ever took a cognitive test. I took it three times. It’s actually a very hard test for a lot of people. It wasn’t hard for me. But it’s a cognitive test,” he brought up in the middle of a Cabinet meeting last month.

“It starts off with an easy question. And by the time you get to the middle, it gets tougher,” he said. “By the time you get to the end, very few people can answer those questions. They get very tough mathematical equations and things.”

This is an insane thing to say about the Montreal Cognitive Assessment. Like a mind bogglingly stupid thing to say. It's got questions like "can you remember these 5 words?" And "Can you draw a cube?" There are zero mathematical equations, it's meant to be a quick test to see if someone is mildly cognitively impaired.
