SAT II, Math Level II

As it just so happens, I totally have this thing covered--as in it
only covers through trig/pre-calc, apparently. I guess it really is
"Mathematics Level 2," not "Calculus Level 2" or something. I suppose
I was confused or something. So...that should be easy.

Of course, though, it's a good idea to look over the stuff that it
says it covers just to be sure that I have a handle on everything,
right? Well, so I realized that standard deviation will be on it, so I
just looked that up and I'm set. Went through the practice problems.
Got them all right.

Except for one. Because, apparently, never having really done matrices
is *finally* coming back to bite me. In a hard manner. Because cross
products don't count. Well...I just went through some summary online.
Hopefully I'll be set. I guess I'll find out too early tomorrow
morning.
