Okay, this is bugging me

Today's the med math test. Originally, it was scheduled for our first day back, but someone took pity on us and moved it to today. The primary impact of this is that everyone's had even more time to get all worked up over it.

A classmate brought a question to me yesterday from a "brain buster" sheet. The nursing tutor who handed out said sheet didn't even know how to solve it. I'm actually reasonably sure it's not solvable as written. ( Cut for lengthy geekitude )

Um, so hopefully no questions like that on the test, or no more than two. Need a 90% to pass, after all.
