I don't know how old your son is, but those are the kinds of scores that may be associated with a strong (i.e. genius level) math ability.
I'd like to put in a gentle note saying that very high scores on segments of an IQ test don't equate to genius. Genius is a trait that's poorly understood, but it's certainly complex and not measurable with a simple set of tests.
I react a bit to this type of phrasing because it can end up putting a lot of the wrong kind of pressure on kids.
OP, did your son stop trying or get tired on the parts of the test where his scores were average? Does he have a learning disability?
