I got a B!

So i got my paper back today, i scored a 224/250. I guess thats not bad, its actually pretty good compared to how i was writing at the begining of the semister. But why couldn't she give me one more point so i could have had an A? I dont quite understand that, because it really did turn out great. I think i am going to talk to her and see if i can get that extra point back, i really want an A! I just really feel that this is an A paper, so its not fair if its got a big B on it. I guess it is the highest possible B, but still i was onlt one point away from an A!!
