Cashing It In

I may be cashing in early.  I've been working on the old problem for about two hours and find that my mind is wandering and I'm surfing other parts of the web.  I've notified my teacher that I'd like to make a few extra points on it, is there anything I can do.  Tomorrow noon is it for me anyway.  I may know my grade for this class by Tuesday afternoon.  Makes me nervous because it may mean the difference between a B and a C.  Grrr.
