Teacher is losing my assignments, it's affecting my grade??!

<p>So far, my APLAC teacher has lost 1 quiz, 1 essay and several other homework assignments.
Some of them are assignments she checked off, which I have no control over.</p>

<p>This is incredibly annoying..so far I have a B in that class because of it.
I am not the only person this is happening to, either. No matter what we try to argue, she just says it's our fault for not ensuring she checked it off or had it.</p>

<p>What do I do? I have no real way to prove that I actually turned in the assignments. The essay was a timed write essay that we wrote in class and turned in at the end of the period.
The quiz, well, I'm not sure how she lost it, but I was there the day it was taken. </p>

<p>I think the homework assignments may be a lost cause. She's known for being incredibly disorganized, and she probably recycled them at some point.</p>

<p>EDIT: It's already the end of the semester so I don't have any other assignments that could average out the loss of points.
She only just started grading assignments, she's been behind for about 2 months, so I honestly had no idea these were missing for quite a while.</p>

<p>Could you try talking to a guidance counselor or an administration official with other students who have had the same problem?</p>
