A professor who is less knowledgeable in certain subjects than a student What is a proper way of showing academic knowledge with assignments when your professors and or school is not on par with a particular students knowledge, so-to-speak?

A student is extremely smart but lacks communication skills due to a disability and is completing advanced work when it is not required. In return, the professors have become egotistical and grade his papers for made up biased issues which have been confirmed to be incorrect grading from other members of the field.

How might a student handle a situation such as this and yet still prosper and graduate with a network of potential workplaces when the professors cannot handle someone who knows more then they do and go after him to encourage failure?
If you have communication issues because of a disability, and it is interfering with your coursework, at least in the US, you would approach the office that handles disabilities.  They will work with you to get the disability officially documented, and then you will work with them to discuss appropriate accommodations with your coursework and your instructors.
