Just as a guess, I'd say he knows a thing or two, or maybe even three orders of magnitude more about science than the Senator's Son -- who managed to get a spectacular C- in a 101 level science class, his only college level science course.
Just guessing of course, but then again, Schmitt does not have a Nobel Prize or even an Oscar like the Senator's Son does. ;~))
IIRC, it was in "Earth Science."
