post lost

I sign on to my school sight and see the grade has posted for the last class.
i click on and see the final project i turned in did not completely download . the teacher did not let me know of the problem. i have checked the sight for grades every couple days. and nothing.
so i lost 250 points from my possible grade.
this sux
i spent 4 hours Sunday morning after finishing work at 6am, completing it and making sure it was turned in since i would not get back to the computer before it was due. I saved the paper.
and printed out a copy and left work.
and to day i find out it was for nothing.
I am so made right now
so i go to resend the paper. it is nowhere on the computer
i call home and have James look for the copy i have and it is not at home
it is not in the car.
the teacher posted a note today " Mk turn in appendix D so i can turn in your grade." this is at 10am
i do not see the note till after i get to work at 6pm
grades have to be turned in by 2pm
I am so screwed
look i am sorry for the rant.
