Section 504 was crucial to my education back in the late 90's. My mom had to play that card repeatedly with my school so that my grades would not be affected for class participation or oral presentations. I also had to use it in college for my public speaking requirement in undergrad, wherein I had to present my case to the dean. It felt humiliating but I was able to take the class with our fear of failing. I've recommended to several others over the years to utilize this while in school. I feared this would be coming.
