Posting my observation here:
I’ve sat in on my mother taking this test a few times over the last 5 years or so. I’m convinced that the first, secret part of the test is whether or not you’re insulted by the suggestion that this test is in any way difficult.
Because it’s not difficult at all - if you don’t have at least some dementia.
What it means that Trump was bragging about his results on this test is left as an exercise for the readers.
