I have a 24 year old that loves to have a companion work on the computer with him. He is in on-line school (Harvard edX) with a on line tutor and needs help due to vision impairments.
He is easy to hang with. You may also work with his PE coach and PT/OT and speech therapist.
You don't need experience but this is a great learning experience if you want.
He knows sign language so plus if you do (Not mandatory)
