I know there are some ways the school can accommodate you, in the US. There's the IEP (individualized education plan), and its junior, the 504 plan. The biggest limit to these setups is our imagination. What has the school offered to do for you?
My girlfriend is allowed to have extended time on tests, and is allowed to take tests in rooms of her choosing. I've also heard that teachers will give you a copy of class notes. I've wondered if it would be possible for me to sit-in on identical classes, since schizophrenia and ECT can affect memory, and since schizophrenia can affect attention.
