Don't worry so much about it if you can. It's not a test as in right and wrong answers. The point of Neuropsychological testing is not to see if you are pretending to have symptoms (why would we do that anyway

). It's more about evaluating your strengths and weaknesses in different areas and then taking the steps, if needed, to receive appropriate guidance regarding recovery and treatment. Just do the best you can. As Almost has said, be prepared that it will be a little draining. Request a copy of the results when they're available.
