Jenny glances up from the biology text as the teacher comes in, then closes her book and puts it away, pulling out the proper textbook.  AP Math had conflicted with her chemistry course, and though she didn't mind an easy class, she really wished she were in AP.<br/><br/>She blinks a bit as the equation goes onto the board, then looks around at everyone else.  Those paying attention mostly have confused or lost expressions on their face.  Was the teacher serious?  That was easily a college-level equation, not typically something for soph math class.<br/><br/>She waits for another moment, and when it becomes apparent that no one else is going to raise their hand, she tentatively puts hers in the air.
