I definately would not do that. LOL I'd actually pay $25 to NOT take the test.
However my oldest son is a math wiz (he
aced the math section of the SAT... yep, don't know where he got that math talent)
and he'd love to do stuff like that just for "fun". Weird... LOL And like Col, he is planning on being a structural engineer. But I'm "making" him get a minor in math at college just to give him some more options.
