Actually they’re not offered in the same way everywhere even if they are a thing in every institution. I know at my school in particular there is a limit to how much time you can get for an exam. I was talking to another user here who said his brother was unable to attend college because they don’t have oral IEPS for the exams in the major in which he would’ve been interested in and an IEP is not always practical for a class given the structure of that class. You may see a clause written somewhere that implementation of the IEP is at the discretion of the professor. It’s not something a lawsuit will necessarily fix. Higher institutions do leave kids behind.
