The first thought that comes into my bipolar mind is: "Do you have a therapist or some sort of counselor you can address your concerns with and maybe, then, sort of get them out of the way enough to be able to concentrate more on your studies?"

Second, is your medications working sufficiently?

Sorry, I had to get those issues out of the way first.....

I, too, have trouble concentrating sometimes. But I'm not in school anyway.

Would it help to read the information out loud to yourself? Even while you're writing, also saying the words?

One idea anyway. Anybody else?
