Why won't my school help me? I'm a Sophomore in high school and i failed Algebra in freshman year, so my dad got me tested for any learning disabilities, and as it turns out I have dyscalculia and A.D.D. I have all the paperwork and me and my dad have gone to the school multiple times and told them to take me out of both my algebra and geometry class and instead put me in a double algebra class. I just don't understand why they won't? It could actually help me, but they don't want to

Keep pushing them to do something.  If they don’t, go above them to the school board.  They have to follow your needs.
