I've fought for years to get accommodations that I was legally obligated to, (504 Plan) fought with a school, (they were actively refusing to give accommodations, illegally) for 3 years, before giving up and switching schools.

The next couple of schools I tried were not well equipped to provide accommodations, albeit not malicious, (in one case not telling anyone until two months in)

Even after I finally got what I was legally owed, I still had to put up with often writing assignments by hand, (I have fine motor coordination disorder, as the commenter above mentioned), including an entire test. (One of the end of year ones for my sophomore year)

I also have CAPD, which allowed me to skip taking Spanish class, after two years of fighting for it. (I failed the first year of Spanish for obvious reasons, I had to retake it the next year.) (This was at the first school, I don't know why I was able to get this accommodation but not the others, I was in middle school)
