Enroll him in a tough "weed out" class, just the one, and see if he can hack it. If he can't, then the question will be answered for him. In a lot of competitive fields, the schools have weed out classes to eliminate those who will likely not succeed.
Of course, if your son has any claim to being a minority, there are many, many jobs for mediocre "rocket scientists" at NASA. I knew many of them. Don't get me started.
I know it is not always well-received on these forums to put in a good word for the black race --- and with all the politically correct social engineering and mass brainwashing that takes place these days, to the effect of the African race being the best thing that ever happened to this planet, paragons of virtue and strength both physical and spiritual, it's entirely understandable, I get just as sick of it as anyone else because it's so overblown and dissent is forbidden --- but here goes...
I found repeatedly in my working life, that for some inexplicable reason, many black
women (
women, not men) were almost
supernaturally good at math and accounting. I've never seen anything quite like it. It's every bit as profound as the usual Asian stereotypes. I even heard one of them comment on it ---
"did you ever notice how many light-skinned black women are good at math?", and no, I don't think she was playing the
"let's all boost each other" card that so many of them do. I haven't seen the film
Hidden Figures but I'd be interested to see it. Math proficiency isn't the kind of thing you can fake.
I've wondered if it could be something in the way the different racial genes combine, and many "light-skinned" blacks are far more white, genetically, than they are black.
