So the chlorox wipes wiped out the dirty stuff--the bad grades! That's great!
I have no idea how it is you maintain your composure. I would be furious day in and day out. I don't think DD's 504 is being followed either, and I was never even given an updated copy but at least in her case, poor grades or missing work don't really affect her at this point, other than teaching her to be careless and that it doesn't matter if she does or does not complete work. Luckily I think the school's plan is to write an IEP, but now we have the problem of her pediatrician not sending the 6 pages of ADHD checklists that the school insists upon.
