Just a wild guess from a B.S. in Psychology, 1972:

I mistook "from a" for "from the" and froze for a second.

That's a joke, just a joke :^)

You have discovered why Bachelors of Science never write their degree abbreviation after their name the way MSs and PhDs do. But the one's just "more" and the other's "piled higher and deeper."
