Please, oh please, say this is not for real.
How did you manage studying for the LSAT?
Man, if you are ACTUALLY concerned about dealing with a learning disability, go to a doctor.
I would hope one seeking to uphold the law as a professional might consider this route, as opposed to swindling prescriptions.
My little brother has ADHD and was only (by a DOCTOR) medicated for a short period of time when he was in first grade. After that, he learned coping skills, like starting everything early, taking breaks, working with other people around, and getting enough exercise so he wasn't antsy. You might try that approach, if you are really worried about the pressures of law school academics.
If you're just being a $#%!, well, quit it.
